Check all of the possible first steps in factoring a polynomial with four terms. A. factor out a GCF

B. factor the difference of cubes

C. factor a sum of cubes

D. factor a difference of squares

E. factor a perfect-square trinomial

F. factor by grouping

The steps in factoring a polynomial with four terms are:

F. factor by grouping

A. factor out a GCF

E. factor a perfect-square trinomial

D. factor a difference of squares

Group the polynomial into sets of two. Since there are 4 terms, you can group it into 2 sets of 2 terms. Find, the GCF of each set and factor it. You can continue factoring until there is no more term to factor.
