Differential Equations - Bernoulli Problem

  1. Feb 6, 2007 #1
    1. The problem statement, all variables and given/known data

    Solve the equation [tex] y' = \frac{2xy}{x^2-y^2}[/tex]

    2. Relevant equations

    The Bernoulli multiplier thing which I don't feel like typing out.

    3. The attempt at a solution

    I'm attempting to separate the equation so I can have y and dy on one side and x and dx on the other, but the denominator is making that really hard for me to do. Any ideas on how to separate it? Thanks.

    Something like u=y/x and so y' = xu'+u. Divide the numerator and denominator of RHS by x^2 to get into the u form. Just make sure you substitute away all the y and y' terms.
