-4x^3-4x-3

Explanation:

(4x-3)-(x^3+2x)(4)
First, distribute everything in the parenthesis. For the first parenthesis, you can take out the parenthesis because you're basically distributing everything in the parenthesis by 1 which won't make a difference.
4x-3-(x^3+2x)(4)
For the second parenthesis, you can either distribute the -1 or 4 first. In this case, I will distribute the negative (-1) to the parenthesis first.
4x-3+(-x^3-2x)(4)
Now I'm going to distribute the 4.
4x-3+(-4x^3-8x)
Now we can remove the parenthesis.
4x-3-4x^3-8x
The rest is just combining like terms.
-4x^3-4x-3
