Factoring Polynomials __ STAAR Review

Factoring

1. Factor the GCF if possible

2. Identify the number of terms

3. Determine the best strategy to factor.

​C --- 12	​(+/-) B --- +7
​1, 12	​1+12 = 13
​2, 6	​2 + 6 = 8
​3, 4	​3 + 4 = 7

​Factor the GCF first and determine the best method to use to factor
