Integration by Substitution Question (1 Viewer)

Hi BOS'ers,

I'm having trouble with this question:
"Find the area bounded by the curve y=x(x^2-4)^3 and the x-axis"

I always seem to get 32, when the answer is 64, and I can't figure out what I'm doing wrong.

Thanks.

The graph is odd so perhaps you forgot to times the area by two?

That must be why, cheers man!

Assuming that you integrated and subbed in the limits from 0 to 2 correctly of course.
