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 + 9 x^3

228 x^4 + 1140 x^3

- 1131 x^3 + 4 x^2

- 1131 x^3 -5655 x^2

5659 x^2 – 6x

5659x^2 + 28295x

-28301x

Thanks.
