Solution for x^2-40/x-8-x^2-5x/x-8 equation: 


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

x^2-x^2-(40/x)-((5*x)/x)-8-8 = 0

x^2-x^2-40*x^-1-8-8-5 = 0

-40*x^-1 = 21 // : -40

x^-1 = -21/40

-1 < 0

1/(x^1) = -21/40 // * x^1

1 = -21/40*x^1 // : -21/40

-40/21 = x^1

x = -40/21

x = -40/21
