Verified Answer :

Answer:

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

Step-by-step explanation:

The given expression is \(-8x^3-2x^2-12x-3\)

First of all we make groups

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

Take GCF from each group

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

Now, we can factored out the common term

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

Hence, the resulting expression is

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