Another U-Substitution Problem
Problem: $(t+1)^2/t^2$. Substitution. No Integration by Parts.

Attempt: I don't see any easy way :\

substitution? why make this harder than it really is ?

$\int \frac{(t+1)^2}{t^2} \, dt$

$\int \frac{t^2 + 2t + 1}{t^2} \, dt$

$\int 1 + \frac{2}{t} + \frac{1}{t^2} \, dt$

$t + 2\ln|t| - \frac{1}{t} + C$
