    Integral question...

    Evaluate the integral. (Remember to use ln|u| where appropriate.)


    I got ln(x-1) - 1/2(x^2 + 16) - 1/4 arctan (x/4) + C for an answer but it was marked wrong....anyone know what I did wrong?

    \ln|x-1| - \frac{1}{2}\ln(x^2+16) - \frac{1}{4}\arctan\left(\frac{x}{4}\right) + C
