Factor the following.

E

Step-by-step explanation:

(3x^2 - 8) (3x^2 + 8)

You can get to the original equation by:

3x^2 * 3x^2 = 9x^4

-8 * 8 = - 64

9x^4 - 64

E. (3x^2-8)(3x^2+8) is the correct answer.

Step-by-step explanation:

To factor this we use the difference of two squares formula because there are no common terms here.

9x^2-64

The square root of 9x^2= 3x^2

The square root of 64 is 8

(3x^2-8)(3x^2+8)

= 9x^2-64

You get back the answer. So it's correct.
