    Integrals

    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.
