Question

Factor -8x^3-2x^2-12x-3 by grouping. what is the resulting expression? A. (2x^2-3)(4x+1) B. (-2x^2-3)(-4x+1) C. (2x^2-3)(-4x + 1) D.(-2x^2-3)(4x +1)​

Answer 1

The correct option is D

Explanation:

The given expression is:

-8x^3-2x^2-12x-3

Group the first two terms and last two terms together.

(-8x^3-2x^2) (-12x-3)

Take out common from each group

-2x^2(4x+1)-3(4x+1)

(4x+1)(-2x^2-3)

Thus the correct option is D....
