Need help using substitution before integration

  1. Sep 3, 2014 #1
    Hi I just started calc 2 and am stuck on a problem. integral ln(x+x^2)dx. They want to use substitution prior to integrate by parts, but I'm completely stuck. Can anyone help explain how to solve?

    I'd use the rules of logs first. Factor. x^2+x=(x+1)*x. So? How can you write log(x^2+x) in a simpler way?
