A. x(x – 3)

B. x(x + 3)

C. x(x – 1)

D. x(x – 7)

E. x(x + 7)

F. This polynomial cannot be factored using the GCF method.

Factor problem 8 by grouping.

8. 8x^2 + 47x + 28

A. This polynomial cannot be factored by grouping.

B. (3x + 7)(5x - 4)

C. (3x - 7)(5x - 4)

D. (3x + 7)(-5x + 4)

E. (-3x + 7)(-5x + 4)

F. (3x + 7)(5x + 4)

Factor problem 12 by using the difference of squares method.

11. 36x^4 – 4x^2

A. (6x2 – 2x)(6x2 - 2x) = 4x2(3x - 1)(3x - 1)

B. (6x2 + 2x)(6x2 + 2x) = 2x2(3x + 1)(2x + 1)

C. This polynomial cannot be factored by using the difference of squares method.

D. (-6x2 – 2x)(-6x2 - 2x) = 4x2(-3x - 1)(-3x - 1)

E. (6x2 – 2x)(6x2 + 2x) = 4x2(3x - 1)(3x + 1)

F. (-6x2 + 2x)(6x2 - 2x) = 2x2(-3x + 1)(3x - 1)

12. x^2 + 100

A. (x + 10)(x – 10)

B. (-x + 10)(x – 10)

C. (x + 10)(x + 10)

D. This polynomial cannot be factored by using the difference of squares method.

E. (x - 10)(x – 10)

F. (-x + 10)(-x – 10)

Factor problem 15 by using the perfect squares method.

15. x^2 – 3x + 16

A. (x – 4)(x – 4)

B. (x – 4)(x + 4)

C. (x + 4)(x + 4)

D. (x + 4)(x – 4)

E. (-x – 4)(-x – 4)

F. This polynomial cannot be factored by using the perfect squares method.

(I have gotten "This polynomial cannot be factored by using the..." on all of these questions, so I'm just trying to make sure if I'm right.)
