1. 2.3 Factor and Solve Polynomial Expressions Review (cont.)
Pg. 76

2. Factor by Grouping
Used when there is four terms in the polynomial to factor
The object is to see if there is a common GCF between the two groups

3. Grouping

5. Factoring Perfect-Square Trinomials
If the first term and the last term of a trinomial are perfect squares but there is a center term
It can not be the difference of perfect squares but it may be a perfect square trinomial
a2 + 2ab + b2 = (a + b)2
a2 – 2ab + b2 = (a – b)2

6. Sum and Difference of Cubes
Just like with the Difference of Perfect Squares…….this must be a binomial.
But now the 1st and 2nd terms are perfect cubes
These are formulas, answer is completely factored
