Question

Quizplus · Accepted Answer

The common factor between 11(a-b) and 2(a-b) is (a-b), therefore the greatest common factor is (a-b). The greatest common factor is the largest factor that both terms share. In this case, both terms have a factor of (a - b), so that is the greatest common factor. Choices A, B, and D are incorrect because they do not fully factor out all common factors between the two terms.
