Solution for X^2-9/x-3=0 equation: 


D( x )

x = 0

x = 0

x = 0

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

X^2-(9/x)-3 = 0

X^2-9*x^-1-3 = 0

-9*x^-1 = -(X^2-3) // : -9

x^-1 = (3-X^2)/(-9)

-1 < 0

1/(x^1) = (3-X^2)/(-9) // * x^1

1 = x^1*((3-X^2)/(-9)) // : (3-X^2)/(-9)

-9*(3-X^2)^-1 = x^1

x = -9*(3-X^2)^-1

x = -9*(3-X^2)^-1
