Solution for X-11/x^2-121 equation: 


D( x )

x^2 = 0

x^2 = 0

x^2 = 0

1*x^2 = 0 // : 1

x^2 = 0

x = 0

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

X-(11/(x^2))-121 = 0

X-11*x^-2-121 = 0

-11*x^-2 = -(X-121) // : -11

x^-2 = (121-X)/(-11)

-2 < 0

1/(x^2) = (121-X)/(-11) // * x^2

1 = x^2*((121-X)/(-11)) // : (121-X)/(-11)

-11*(121-X)^-1 = x^2

x^2 = -11*(121-X)^-1 // ^ 1/2

abs(x) = (-11)^(1/2)*(121-X)^(-1/2)

x = (-11)^(1/2)*(121-X)^(-1/2) or x = -((-11)^(1/2)*(121-X)^(-1/2))

x in { (-11)^(1/2)*(121-X)^(-1/2), -((-11)^(1/2)*(121-X)^(-1/2)) }
