Determine the following integrals:

x(x+2)^{7/2}dx

Would I use the substitution method making U= x+2 therefore the derivative of that is just 1 and then continue on? Or am I completely on the wrong track!

That would be a good substitution, as it will give you:

$\displaystyle \int (u-2)u^{\frac{7}{2}}\,du$

Now, distribute and integrate, then back-substitute for $\displaystyle u$. - Dec 13th 2012, 10:34 AMjason403Re: Integrals
any idea to solve this:
