Are you sure that's the entire problem? Are we given $\displaystyle f(x)$ ?

ha! i wish but no. i just called my friend. apparently you use parts, u = f(x) dv=x, so du= f'(x) and v=x^2/2. so, since integral of udv= uv- integral of vdu. thus, f(x)(x^2/2) minus integral of (x^2/2)(f'(x)).

it was dumb.
