1. The problem statement, all variables and given/known data ∫ ((2t+3)^2)/t^2 dt 2. Relevant equations 3. The attempt at a solution I figured that I would use integration by parts. The problem I'm having is that we haven't actually learned integration by parts, only the u substitution method. I went ahead and read the book on the proof and several examples, but its still a bit new to me so I'm not sure how to approach he problem. u=1/t^2 du=-dt/3t^3 ∫dv∫=(2t+3)^2 dt v=(4t^3)/3 +6t^2 +9t 4t/3 +6+9/t - ∫ ((4t^3)/3 +6t^2 +9t)/t^3 dt Is there a more straight forward way of solving this?
