Factor –8x3 – 2x2 – 12x – 3 by grouping. What is the resulting expression?
(2x2 – 3)(4x + 1)
(–2x2 – 3)(–4x + 1)
(2x2 – 3)(–4x + 1)
(–2x2 – 3)(4x + 1)

Step-by-step explanation:

The expression that we have to factorize in this problem is

And we have to factorize it by grouping.

First of all, we start by factorize a factor from the first two terms, we get:

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

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

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