The problem is given as
[tex]\int\frac{x*e^x}{(x+1)^2}dx[/tex]
I did u substitution with u=(x+1) and du=dx
which gives me [tex]\int\frac{(u-1)*e^{u-1}}{u^2}[/tex]
simplifies to [tex]\int\frac{u*e^{u-1}-e^{u-1}}{u^2}[/tex]
Then I separated it into two integrals
[tex]\int\frac{e^{u-1}}{u}-\int\frac{e^{u-1}}{u^2}[/tex]
Now I'm stuck. I tried doing these separate integrals by parts, but it doesn't seem to be working for me. Am I going in the complete wrong direction with this? Any help would be appreciated.
