Here is the problem I am working on:
Find the quotient and remainder when P(x) = 7 x^6 - 9 x^5 + 8 x^4 + 9 x^3 + 4 x^2 - 6 x is divided by (x + 5).
My answer that I came up with is this.
Q = 7x^5 - 44x^4 + 228x^3 - 1131x^2 + 5659x
R = -28301x
I have done this using Long and Synthetic division and have come up with the same answer every time. Problem is, LonCapa says it is wrong. Anyone know why?
Thanks.

7x^5–44x^4+228x^3–1131x^3 + 5659x

X+5 | 7 x^6 - 9 x^5 + 8 x^4 + 9 x^3 + 4 x^2 - 6 x7 x^6 + 35x^5
-44x^5 + 8 x^4
-44 x^5 – 220 x^4

228 x^4 + 1140 x^3

Thanks.
