A) 9a3b3

B) 9a3b2

C) 3a2b3

D) 3a3b2

B) 9a3b2

Explanation:

Took the test

Answer 2

GCF means greatest common factor. From the word itself, you find the largest common factor for all the terms of the function in order to factor it out. As a result, this simplifies the equation.

For the whole numbers, GCF = 9
For variable a, GCF = a3
For variable b, GCF = b2

Thus, the overall GCF is 9a3b2. The answer is B.
