2. Simplify by factoring out the GCF

3. Factor by Grouping

5. 12.2 Factoring Trinomials in the form When in this form we try to factor into the product of two polynomials by finding factors of c that will add to be b: Factors of 4 are 2,2 or 4,1 Since b = 5, the sum of the two factors is 4 + 1 You need to be careful of the signs ….

6. Factor completely … is there a GCF before factoring the trinomial?
