The difference of cubes formula is explained below along with solved examples in the following section. … WebDec 13, 2009 · Step 1: Identify the GCF of the polynomial. This time it isn't a monomial but a binomial that we have in common. Our GCF is (3 x -1). Step 2: Divide the GCF out of every term of the polynomial. *Divide (3 x - 1) out of both parts When we divide out the (3 x - 1) out of the first term, we are left with x .
