       2      d                2 d                
x + x*y (x) + --(y(x))*y(x) - x *--(y(x))*y(x) = 0
              dx                 dx               
$$- x^{2} y{\left(x \right)} \frac{d}{d x} y{\left(x \right)} + x y^{2}{\left(x \right)} + x + y{\left(x \right)} \frac{d}{d x} y{\left(x \right)} = 0$$
-x^2*y*y' + x*y^2 + x + y*y' = 0

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