Intermediate Algebra 2 Assignment for 1/9

We’ve started the second section of Unit 4, learning about complex and imaginary numbers. This is a new category of number, much like irrational or negative numbers, that mathematicians developed to handle equations that they previously had no ability to solve. We watched two videos to introduce this topic, but I recommend you watch the full story found here.

Your homework tonight is HW 4.9 – Introduction to Complex Numbers. You can find the notes for this assignment here.

Intermediate Algebra 2 Assignment for 1/8

We had our Simplest Radical Form quiz in class today, so the homework is the usual post-quiz assignment: complete one side of HW 4.8 (your choice) for a homework credit, and complete both sides for extra credit on your quiz. You must show all work for extra credit!

Intermediate Algebra 2 Assignment for 1/4

Your first quiz of Unit 4 will be tomorrow (or, if school is canceled, on Monday). You should review the study notes we did in class and complete HW 4.7 – Quiz Review 2 (you can find my solutions here).

And don’t forget to work on some IXL practice!

Intermediate Algebra 2 Assignment for 1/3

We have commenced review for our quiz on Friday, and your homework tonight is HW 4.6 – Quiz Review 1. You’ll have plenty of time tomorrow to ask questions and get some extra practice in. But don’t forget that the IXL modules below would be a great place to start!

Intermediate Algebra 2 Assignment for 1/2, plus a reminder

First, a reminder of the homework protocol.

  • Homework is assigned every day and due the following day. Homework is assigned every day and due the following day.
  • Late assignments will be accepted ONE day late for half-credit.
  • If you are ABSENT FROM CLASS, you are expected to turn in the assignment you would have submitted on that day on the day that you return. You will be given one additional day per day of absence to turn in the assignments you missed.
    • For example: Goofus is present on Monday and absent on Tuesday. On Wednesday, he must turn in Monday’s homework, and he has until Thursday to turn in Tuesday’s assignment. He gets no extra time on Wednesday’s assignment; that is due Thursday also.
  • If you are having difficulty with an assignment, it is your responsibility to arrange extra help. We usually have time to discuss one or two topics in class, but if that’s not enough please come and see me!
  • New for 2018: Any student who has 3 or more unexcused missing assignments will be assigned a lunch or after school detention to make up the missing work. This work will or will not be accepted for credit based on my discretion!

We have a quiz on Friday, January 5 about the first half of the unit, all about working with radical expressions. This will include content from today’s homework: HW 4.5 – Simplifying Radicals with Variables. You can find the notes here and some addition examples in the video here.

Intermediate Algebra 2 Assignment for 12/21

The use of radical expressions as the inverse of exponents extends beyond the power of two. While the square root is the inverse operation for a power of 2, there are cube roots, fourth roots, fifth roots, and so on for other powers. Generally, we call these “Nth roots.” Your homework tonight is HW 4.4 – Evaluating Nth Roots. I’ve uploaded the notes here, and you can check out this video for some more examples (and instructions for evaluating nth roots on the calculator).

Intermediate Algebra 2 Assignment for 12/20

While we did some work with dividing radical expressions on Monday, we expanded on it today to make the observation that, in general, we try not to leave any radicals in the denominator of an expression. The process of fixing this is called rationalizing, and so your homework for tonight is HW 4.3 – Rationalizing Denominators. As usual, you can find the notes here and a video with some extra examples here.

Intermediate Algebra 2 Assignment for 12/19

We continued to work with radical expressions today, this time multiplying (and distributing) them. The homework is HW 4.2 – Multiplying Radicals. As usual, find the notes here and check out some videos of more examples here. You’ll note that this video uses a different method to simplify radicals than what we typically use.

We’ve started Unit 4 today, and this will take us through to January’s exam week. The first part of Unit 4 is more work with radical expressions, including performing operations. Today’s homework is HW 4.1 – Adding/Subtracting Radicals. You can find the notes here, and you should view these videos for some additional examples: Video 1 Video 2.

The answers to the study guide review from yesterday can be found here. Use this to review/study!

Today, you got the second review: HW 3.19 – Test Review 2. You should finish that tonight and refer to the solutions here.

Finally, you can continue to work on the assigned IXL modules below for credit up to the period of the test. After Friday, the gradebook is closed on these modules.

Intermediate Algebra Assignment for 12/13

Your Unit 3 test is on Friday, December 15. Today we spent time reviewing, including making a study guide in preparation for the test. Tonight, you should finish that work, with HW 3.17 – Test Review Sheet 1.

Finally, fair warning: I will not be in school tomorrow, the 14th. Please email me with questions, or plan to come see me before class on Friday!

Our last new content from the unit is HW 3.17 – Using Roots to Factor Polynomials. The notes can be found here. Check out this video for some more examples on writing the factored from of an equation given its roots. If you need a refresher on using your calculator to find roots, check out the video here.

Intermediate Algebra 2 Assignment for 12/11, plus Test Warning

We are wrapping up Unit 3, and our unit test will be on Friday, December 15. It will be cumulative for the entire unit, including graphing/identifying key features of parabolas and solving quadratic equations. Today and tomorrow, we are connecting the first and second parts of the unit together, and we started that today by discussing how to find the key features of a parabola algebraically (i.e., from the equation, without graphing it). We did this via a Desmos activity, so there are no notes, but you could review the method we discussed with this video.

The homework is HW 3.16 – Finding Key Features Algebraically.

Intermediate Algebra 2 Assignment for 12/8

We spent some time in class reviewing the three methods of solving quadratic equations:

  • Factoring (which only works when the polynomial is factorable)
  • Using the Square Root (which only works when there is no “bx” term in your polynomial)
  • Quadratic Formula (which works in all cases, but is kind of a pain)

The notes for our review are here, and the homework is HW 3.15 – Solving Quadratic Equations Recap.

Intermediate Algebra 2 Assignment for 12/7

We discussed today that some quadratic equations can simply be solved using the square root (though with the specification that they still must include a plus/minus, since all* quadratic equations have two solutions). We also looked at an example of creating a quadratic equation from a word problem and solving it, taking care to ignore the answer that didn’t make sense in the context of the problem (the so-called extraneous solution). The notes can be found here, and your homework is HW 3.14 – Quadratic Word Problems. Check out this video for another example of a quadratic word problem involving area, and this video for more on solving equations with the square root.

*Okay, not all. Quadratics that factor to something like (+ 3)(+ 3) = 0 only have the one solution of x = -3.

Intermediate Algebra 2 Assignment for 12/6

We had a pop quiz in class today. I don’t generally like to give pop quizzes, but I really needed to see where we are at with solving quadratic equations before we move on. The quiz will be graded and recorded, but its weighting will reflect the fact that it was a pop mini-quiz and not a full-period quiz that you had knowledge of beforehand.

Your homework is to work on a single IXL modules linked below: BB.10 from the Algebra 1 section of IXL. All I’m asking you to do is to complete it up to a score of 80.

We did some more practice with solving quadratic equations today, so there are no new notes. Your homework is HW 3.12 – Solving Quadratics Extra Practice. See the videos posted in the past few days for extra support on how to approach these problems.

Continuing with solving quadratic equations, today we reviewed the Quadratic Formula. Your homework is HW 3.10 – Solving Quadratics with the Quadratic Formula. Notes can be found here, and you can again find many, many videos on YouTube about the Quadratic Formula, but I recommend this one (and others by that same channel).
