The GCF for each term of the polynomial is .

The product of prime polynomials is .

(x – 2)(x + 1)

(x + 2)(x – 1)

2(x – 2)(x + 1)

2(x + 2)(x – 1)

There are terms to be factored.

Is there a GCF > 1 for the two terms?

Yes, it is 2.

Yes, it is 4.

No, their GCF is 1.

Factor the polynomial completely.12x4 – 42x3 – 90x2 What is the GCF of the polynomial?

6x2

What is the equivalent factored form of 12x4 – 42x3 – 90x2?

6x(x – 5)(2x + 3)

6x2(x – 5)(2x + 3)

6x(x + 5)(2x – 3)

6x2(x + 5)(2x – 3)

The completely factored form of this polynomial is (x2 + 2x + 4).

(x – 2)

(x + 2)

2(x – 2)

4(x – 2)
