    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.
