Homework Help: Partial fraction Intergals

  1. May 20, 2005 #1
    hello, i have the Intergal ∫(5x^2-3x+1)/((x^2+1)(x-2)) dx
    i do not know what to do first, i firstly tried to change to partial fraction but that didn't work to, then i tried substitution technique and again i didn't have anything to substitue that got me any further, i don't know what else to try, somebody please help.

    Determine constants A,B,C so that:
    [tex]\frac{5x^{2}-3x+1}{(x^{2}+1)(x-2)}=\frac{Ax+B}{x^{2}+1}+\frac{C}{x-2}[/tex]
