Need help with this math problem

Andre45 [30]

Hey There!

First you would need to factor out the two.

-4x^3/2 = -2x^3

2x^2/2= x^2

12x/2= 6x

6/2= 3

Now we have.

-2x^3+x^2+6x+3 / x+1

We would then factor with polynomial division, and then we should have.

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

We would then cancel out the x+1

Therefore, the answer would be $\boxed{-2(2x^2-3x-3)}$

Hope this helped!
