Question 557274: Divide 27x^3-63x^2-105x-27/9x+3. I have started this off by doing the long division process. It's kind of hard to show my work on here, but I am having trouble when it comes to dividing the -105x. So far I have my answer as 3x^2+6x. When I divide -87 by 9 I receive -9.67

----
There is a common factor of 3 in the numerator and the denominator.
= (9x^3-21x^2-35x-9)/(3x+1)
----
Divide numerator and denominator by 3 to get
-1/3)....9....-21....-35....-9
..........9.....-24....-27...|..0
-----

Quotient: 9x^2-24x-27
Remainder = 0
===================================

Divide the quotient by 3 to get:
= 3x^2-8x-9
