Tutors, please sign in to answer this question.

1 Answer

The GCF is the Greatest Common Factor - the largest factor that exists in each of the terms. To start, let's factor each term:

3x2 = (3)(x)(x)
6x = (2)(3)(x)
3 = (3)(1)

The largest factor that exists in each term is (3), so factoring it out, we get:

(3)(x2 + 2x + 1)
