question

Factor out the greatest common factor. If the greatest common factor is 1, just retype the polynomial.

key idea

To factor a polynomial, first find the greatest common factor (GCF) of each monomial. Then factor out the greatest common factor using the distributive property.

solution

First, factor each monomial and find the common factors.

The common factors are 3,

and

Multiply them to find the greatest common factor.

The greatest common factor is

Now factor out

(

)

The factored form of the polynomial is
