d 2 2 d
2*x - 2*--(y(x))*y(x) = - 2*x*y (x) + x *--(y(x))*y(x)
dx dx
$$2 x - 2 y{\left(x \right)} \frac{d}{d x} y{\left(x \right)} = x^{2} y{\left(x \right)} \frac{d}{d x} y{\left(x \right)} - 2 x y^{2}{\left(x \right)}$$
2*x - 2*y*y' = x^2*y*y' - 2*x*y^2

y(x) = -\/ -1 + 4*C1 + C1*x + 4*C1*x
$$y{\left(x \right)} = - \sqrt{C_{1} x^{4} + 4 C_{1} x^{2} + 4 C_{1} - 1}$$
