It is assumed that factoring has been introduced in class. In order to factor the students know at this point what Monomials, Bimomials, and Trinomials are.
Name Number of Terms Example
Monomial 1 3x2
Binomial 2 3x2 + 4x
Trinomial 3 3x2 + 4x + 2
Now is the time that a review of adding and subtracting polynomials is appropriate.
The students may not look at this as a review but at this point in Algebra it is assumed that they have been working with combining like terms, as well as the familiarity of the Properties:
Commutative Property of Addition
Associative Property of Addition
Multiplication of Ð1
Note: This may not be a review as the students seem to think that each new lesson is completely new.
