    PF rules forbid us from telling you how to do the question; we can offer hints only. My hint is: try a different integration by parts, because the one you used does not work.

    Indeed I have tried x-3, sqrt(x-3), x^n
    All of the mentioned just do not help me in simplifying the equation, things just get more complicated...
    That's the reason I believe I have done the wrong thing in the calculation...

    You can not integrate (u2-3)n as you did. Write it as (u2-3)n-1*u * u and try integration by parts.
