This is a problem from Temple University's 'Calculus on the Web' site, I am trying to get re-acquainted with first-semester Calculus as I will begin taking Calc II in a month from now. I can't think of how to bring that x down. Logs?

This is a given identity thinger I should be familiar with? I haven't come across it, please let me know the deal.
