Homework Help: Verify an integrating factor for differential equation stuck

  1. Apr 18, 2010 #1
    1. The problem statement, all variables and given/known data
    verify that mu= 1/(y^4) is an integrating factor of: (3x^2 - y^2)dy/dx - 2xy = 0
    and use it to solve the equation.



    2. Relevant equations

    (3x^2 - y^2)dy/dx - 2xy = 0
    first i want equation in standard form right?

    dy/dx - 2xy / (3x^2 - y^2) = 0

    then mu = e^integ (2xy / (3x^2 - y^2))

    but i will stop here because i think im on totally wrong track. I dont see how they get mu= 1/y^4 as integrating factor
