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
5. Re: C4 integration help, please! :)
Why would you do that?

x^1/2(1+x^1/2)= x^1/2 + x
Yes, completely blanked and didn't see that! Thank you for your response

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.
