Solution for z^2-z-11/x-3 equation: 


D( x )

x = 0

x = 0

x = 0

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

z^2-(11/x)-z-3 = 0

z^2-11*x^-1-z-3 = 0

-11*x^-1 = -(z^2-z-3) // : -11

x^-1 = (z-z^2+3)/(-11)

-1 < 0

1/(x^1) = (z-z^2+3)/(-11) // * x^1

1 = x^1*((z-z^2+3)/(-11)) // : (z-z^2+3)/(-11)

-11*(z-z^2+3)^-1 = x^1

x = -11*(z-z^2+3)^-1

x = -11*(z-z^2+3)^-1
