Question

Use the greatest common factor of the following binomial to factor the expression

Answer 1

The Solution:

Given the binomial expression below:

$45a^3-15a^2$

We are asked to factorize using the greatest common factor (GCF).

So,

The GCF of the binomial expression is

$15a^2$

So, we shall factor out the GCF as below:

$45a^3-15a^2=15a^2(3a-1)$

Thus, the correct answer is [option 3]
