I found the solution to be

Integral = (1/2)xe^2x - (1/4)e^2x + C

You got it afnoo_manche but you need to put in your limits too (remember: upper limit is -x^2 and the lower limit =x^1).

There will be no 'C' since you are working with definite integrals, but don't forget to include 'C' if you are dealing with indefinite integrals. Btw, did you work the problem by youself. You can do it in very few steps.

Good luck!
