    Have you tried the integration by parts method? That should be applicable here ........

    Why would you do that?

    x^1/2(1+x^1/2)= x^1/2 + x

    No it wouldn't. You don't have a function of x where the power of x will reduce to 0 by differentiating.

    IBP would work here, but a long winded process for such an easy integral.
