I need help with this integral that was on an AP Calculus BC Practice Test.

$\displaystyle

\int_{1}^{e} \frac{ (x^2+1) } {x} dx

$

This is on the non-calculator section, so it doesn't need to be in decimal format - just simplified would be great.

Maybe even just give me a prod in the right direction as far as which method to use. I tried integration by parts, but got a different answer than what was provided in the five choices.

Thanks in advance!
