Identify the GCF of 9a4b4 - 27a3b3 + 18a3b2.

A) 9a3b3

B) 9a3b2

C) 3a2b3

D) 3a3b2

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.
