Please help me
Write your answer in the form Q(x)+ R(x)/ -2x^2+3x-3,
where Q(x) is the quotient and R(x) is the remainder.

First rearrange and simplify the numerator to:
6x^4 + 9x^3 + 9
Just divide as your would with any long division problem.
If you post your answer I can tell you if you are correct.
Is there something in particular you do not understand?

Just not good at division

I'll try, but the formatting here doesn't allow for easy alignment of columns.
xxxxxxxxxxxxx-3x^2 - 9x - 9
-2x^2+3x-3 |6x^4 + 9x^3 + 0x^2 + 0x +9
------------6x^4 - 9x^3 + 9x^2
subtraction-------18x^3 - 9x^2
------------------18x^3 - 27x^2 + 27x
subtraction-------------18x^2 - 27x + 9
------------------------18x^2-27x + 27
Answer in the form
Q(x)+ R(x)/ -2x^2+3x-3,
-3x^2 - 9x - 9 + -18/(-2x^2 + 3x - 3)
I don't know how you will follow this because of the formatting.
