        2     d            d                       
-1 + 9*x  + x*--(y(x)) - 4*--(y(x))*y(x) + y(x) = 0
              dx           dx                      
$$9 x^{2} + x \frac{d}{d x} y{\left(x \right)} - 4 y{\left(x \right)} \frac{d}{d x} y{\left(x \right)} + y{\left(x \right)} - 1 = 0$$
9*x^2 + x*y' - 4*y*y' + y - 1 = 0
