1. The document provides a warm-up, review, and homework schedule for a math class. It includes 5 practice problems for an upcoming test similar to the test questions. 2. It also reviews binomial sign rules and special binomial products that will be important for factoring, including examples of perfect square trinomials and differences of squares. 3. Students are instructed to write down the special products information for future use and told they will need to recognize the products in both factored and expanded forms.

1. The sum of 2 binomials is 5x2
- 6x. if one of the
binomials is 3x2
- 2x, what is the other binomial?
All Questions are very similar to tomorrow's.
2. 9x6
- 18x4
+ 5x2
2x4
4. (2y2
+ 3xy - 4) - (- 5x2
+ 5xy + 2) =

3. Binomial Sign Summary
(x + 4)(x + 3)
Middle Term Last Term
positive positive
(x - 4)(x + 3)
negative negative
(x + 4)(x - 3)
positive
negative
(x - 4)(x - 3) negative positive
Which term is bigger doesn't matter when both signs
are the same, but it does when the signs are different.
*In this case, because the negative coefficient
is larger than the positive.
*See above

4. Special Products are three types of binomials that occur
frequently in algebra. Because of this, you will benefit by
memorizing their patterns. It will help a great deal when
we start factoring (soon). Here they are:
P.S. You'll want to write this down.
You should be able to recognize the products both ways.
(x2
+ 16x + 64) = ( )2x + 8 (4p2
+ 16pr + 16r2
) = ( )22p + 4r
