Determine the following integrals:
x(x+2)7/2dx

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!

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

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

Now, distribute and integrate, then back-substitute for $u$.
