I am having problems with a couple of integration by parts questions

I have answered but my answer does not agree with the provided answer (which is answer only, no working)


Maybe someone can give me their worked answer so I can compare?


\(\int x\sqrt{4-x}\;dx\)

Note: there are many different ways to write the result.  Are you sure what you did is incorrect, or is it just expressed differently from the answer supplied?

Thanks again Alan,


Again, I did not do the initial integration properly.  

I must have been off with the pixies yesterday.

I'll try some more today.

Hopefully, the pixies will be covering from yesterday's party.


Thanks so much.
