Factoring GCF Factor polynomials by using the greatest  common factor.

Recall that the Distributive Property states that ab + ac =a(b + c) Recall that the Distributive Property states that ab + ac =a(b +  c). The Distributive Property allows you to “factor” out the GCF  of the terms in a polynomial to write a factored form of the  polynomial.

Factor out the GCF:
