    Non-exact differential equation help

    Hey everyone,

    I have this problem y(x-y-2)dx + x(y-x+4)dy = 0

    I get an integration factor of y^3 but when I multiply both equations by this they are not exact, what am I doing wrong?

    Thanks

    Check your sign. I believe it should be \frac{1}{y^3}.
