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