# Remainder Theorem - Wrong book answer? watch

1. ___
2. I don't see the issue here.
3. (Original post by Dooderman)
The question is as follows:

Find the remainder when divided by (x+1):
f(x) = x^5 + 2x^2 - 3

The way I have attempted to solve the question is as follows:

f(-1) = (-1)^5 + (2(-1 x -1)) - 3
(-1)^5 = -1
(2(-1 x -1)) = 2
-3 = -3

-1 + 2 - 3 = -2 is the remainder.

The answer in the book is -2.

Is the answer in the book wrong, or am I doing something incorrectly?
You said you got -2 as the remainder and the answer in the book is -2...can't see anything wrong here!
I also get -2.
