Homework Help: Can someone please integrate this (hard) (not sure if even possible)

  1. Oct 14, 2012 #1
    Please intergrate: (x+3)/(x^2+4x) is it even possible to integrate this?

    The question in the book was (x+2)/(x^2+4x) and it can nicely be integrated to 0.5ln(x^2+4x), but by changing the 2 to a 3 f'(x) don't go into each other. if you know what i mean.

    You are not supposed to do a student's homework---just give hints.

    Right. Please just give hints next time and don't solve the entire problem (even if it's not posted in the homework section: if it looks like homework, then don't give full solutions).
