Homework Help: Derivatives of a higher order - Satisfying the equation

  1. Oct 15, 2013 #1
    1. The problem statement, all variables and given/known data

    Show that y= xex satisfi es

    A(d2y)/dx2 + B(dy/dx) + Cy = 0

    for suitably chosen values of the constants A, B, and C.

    2. Relevant equations


    3. The attempt at a solution

    Please see the attachment. I get to a point where I need to find the value of A, B and C but cannot as I'm dealing with x2 terms.

    Help would be much appreciated.
