(y2-x2)dy = 3xydx
dy/dx = 3xy / y2-x2    _______________1
since it is non homogenous
Let  y = vx
diff. w r to. x  dy/dx = v + x * dv/dx
now equ 1 becomes
v + x*dV/dx = 3vx^2 / x^2 (V^2 - 1)
on solving
v^2 -1              dx
____   dv =   _____
v(4-v)                x
Integrate on both you will get the solution.
