Homework Help: Integral (maybe simple maybe hard)

  1. Oct 29, 2014 #1
    1. The problem statement, all variables and given/known data
    integrate (t^2) / (1+2t) . Wolfram alpha gave this as the answer: http://www4a.wolframalpha.com/Calculate/MSP/MSP957620di145hih25dggd00002hc5g230hb2h25hd?MSPStoreType=image/gif&s=24&w=229.&h=36. [Broken]

    3. The attempt at a solution

    I tried a u-substitution and couldn't arrive at a solution. Any other suggestions! Int by parts doesn't seem to work either!

    The only easy method that comes to mind for me is to split the integrand into easier parts by long division.

    The substitution u = 1+2t should work. I'm guessing that's what you tried, but you messed up somewhere along the way. Show your work.
