Intermediate Algebra 2 Assignment for 12/14

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.

Intermediate Algebra 2 Assignment for 12/5

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 our work with quadratic equations, today we have HW 3.11 – The Quadratic Formula and Simplifying Radicals. The notes can be found here and more examples of simplifying radical expressions can be found here (and yes, she is writing backwards on a pane of glass).

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).

Intermediate Algebra 2 Assignment for 11/30

We’ve started the second part of Unit 3 today, working with quadratic equations from an algebraic — instead of a graphical — approach. Your homework tonight is HW 3.9 – Solving Quadratics by Factoring. You can find the notes posted here, and there are many videos on YouTube you could check out for extra examples: I recommend this one.

Intermediate Algebra 2 Assignment for 11/28

We will have our first quiz on Unit 3 tomorrow, all about graphing and identifying key features of parabolas. Finish HW 3.7 – Parabolas Quiz Review for a homework credit (you can find the answers to it here).

I’d also recommend that you continue to work on the IXL modules below. Many of you still haven’t gotten them up to the expected scores!

Intermediate Algebra 2 Assignment for 11/27

We will have a quiz on the first part of Unit 3 on Wednesday, November 29. It will cover all of the work about parabolas that we have done, including today: Finding key features with the calculator. The notes from today can be found here, and your homework is HW 3.6. If you need a refresher on using your calculator, check out the video here (it uses a non-parabola graph, but the commands are the same).

We did some IXL practice in class today while I met with students individually. Whatever modules you didn’t finish in class are due on Monday (for a separate HW credit each!)

 

Intermediate Algebra 2 Assignment for 11/20

The parabolas we’ve been working with in class so far are graphs of quadratic equations, of the form f(x) = ax^2 + bx + c. Today, we practiced using graphing technology (either your graphing calculator or http://www.desmos.com/calculator) to graph parabolas and identify the key features. You can find the notes here, and your homework is HW 3.4 – Graphing Parabolas.

We explored parabolas some more with yet another Desmos activity today, formalizing our vocabulary for the key features of the graph. You can find the notes uploaded here, and the homework for the weekend is some practice at identifying these key features: HW 3.3 – Parabola Key Feature Vocabulary.

Intermediate Algebra 2 Assignment for 11/7

The last topic of Unit 2 is about solving equations with Rational Expressions. This particular section has importance to the fields of circuitry and optics, where the total resistance of a parallel circuit and the calculation of the focal length of a lens can both rely on solving equations rational expressions in them.

Your homework is HW 2.16 – Solving Rational Equations and you can find today’s notes posted here. You might also want to check out this video or this video for some examples of worked out solutions to such equations.

Your second quiz of the unit is on Monday. It will be cumulative for the full unit so far, so expect to see complex fractions and operations with rational expressions.

Your final review is HW 2.14 – Quiz 2 Review (Day 2). You can find the answers here. This will be collected on Monday, as usual.

Work on that, review your notes, and work on some IXL modules for some additional practice!
