Easy integration qn

  1. Mar 2, 2009 #1
    1. The problem statement, all variables and given/known data
    int(1/(2x+2x^2))dx


    3. The attempt at a solution
    can someone help me where to start with this one i know its not hard, but i cant find out what to factorize then do parts??

    ive forgotten this simple integration stuff, do i make it 1/2x(x+1) then integrate by parts?? anyways the answer is -(1/2)ln(x+1)+(1/2)ln(x) i have to use parts dont i, or can i separate some how??

    Since you've factorized the denominator, seems like you should integrate by partial fractions, not by parts.
