Answer:

(–2x2 – 3)(4x + 1)

Step-by-step explanation:

it's D on edg

Answer 2

Answer:

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

Step-by-step explanation:

The expression that we have to factorize in this problem is

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

And we have to factorize it by grouping.

First of all, we start by factorize a factor $-2x^2$ from the first two terms, we get:

$-2x^2 (4x+1)-12x-3$

Then we factorize a term -3 from the last two terms, and we get:

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

Now we can group the similar terms, and we get:

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

So the correct option is option D, the last one.
