Can someone show me the steps to finding the integral of (x+1)/(x^2+2x) [ln(x^2+2x)] dx

I'm not sure where to begin because I don't have any integration rules with the lnx

The second one, the first on is not so true...

in second integral use integration by parts... - Aug 4th 2010, 08:18 PMjohn-1
could you show me the steps please? I only have the answer with me in my text but no steps

Using the substitution , we have:

TheCoffeeMachine, in your second step, why did you put (x^2 + 2x) / (x+1)? Where did that come from? mostly confused about 2nd step

If then

He then subbed this into the integral for dx!
