Integration by parts

  1. Sep 8, 2011 #1
    1. The problem statement, all variables and given/known data


    ∫▒〖(2x-1)e^(-x) 〗 dx



    I don't want to butcher this but I know you use integration by parts, I just don't know how to do this one in particular because i is one of the simple ones I was told. Please Help
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    Re: Integration

    Integration by parts is correct. Let u=2x-1 and dv=e^(-x) dx. What is du? What is v?
