Solución

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

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