A5 C-Level Review- Kelly

Last updated over 4 years ago
26 questions
This task is to help you review for the test. On the test, you should not expect to see any of the text or videos that remind you how to complete a problem. Some questions have been added to help you remember how to do certain parts; they are labeled supporting questions.

You should have paper and pencil handy; it would be helpful for you to write down anything that you didn't remember on your own so you can use it for notes on the test.
A5-1 Multiplying Binomials
Vocabulary reminder:
Factored form is when we are multiplying factors; in this case, binomial factors. Factored form looks like this:


Standard form is what results when we multiply the binomials (either with FOIL method or area model or knowing the pattern), and combine like terms to simplify. It looks like this:

1

Given the factored form


Multiply to find the standard form.

Given a factored form


What is true about the standard form?

This is a supporting question (intended to help you learn) and you will not see questions like this on the test.

If you had any trouble with #1-5, watch the video below and/or return to the work for A5-1 (November 30/December 1)
A5-2 Factoring quadratics when a=1 and all numbers are positive
In order to figure out which pair of numbers will add to the middle term, you need to know the factors of numbers, or have a system to find all the factors. The video below shows you how to factor numbers in pairs, so you can easily find the pair that adds up to your middle number. (skip if you already know)
