$$\frac{10x^4y^3 + 5x^3y^2 - 15x^2y - 25x^2y^4}{-5x^2y} = -\frac{10x^4y^3 + 5x^3y^2 - 15x^2y - 25x^2y^4}{5x^2y} $$                                                       $=-\left(\dfrac{10x^4y^3 + 5x^3y^2 - 15x^2y - 25x^2y^4}{5x^2y}\right) $ 
                                                       
                                                       $=-\left(\dfrac{10x^4y^3}{5x^2y} + \dfrac{5x^3y^2}{5x^2y} - \dfrac{15x^2y}{5x^2y} - \dfrac{25x^2y^4}{5x^2y}\right)$
