    Hi. In the beginning of your answer for part B, at the 6th line you write that the integral of x*e2x is equal to the difference e2x/2 - e2x/4.
    At first, it seemed to me like you tried to solve the previous equation for the integral, but this result doesn't seem to follow in any way, and furthermore it's wrong as it would imply that the integral of xe2x w.r.t. x, is e2x/4, which is false!
