Solución

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

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