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

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

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

X^2-22*X-121*x^2+121 = 0

(X^2-22*X-121*x^2+121)/(x^2) = 0

(X^2-22*X-121*x^2+121)/(x^2) = 0 // * x^2

X^2-22*X-121*x^2+121 = 0

-121*x^2 = -(X^2-22*X+121) // : -121

x^2 = (X^2-22*X+121)/121

x^2 = (X^2-22*X+121)/121 // ^ 1/2

abs(x) = ((X^2-22*X+121)^(1/2))/11

x = ((X^2-22*X+121)^(1/2))/11 or x = -(((X^2-22*X+121)^(1/2))/11)

x in { ((X^2-22*X+121)^(1/2))/11, -(((X^2-22*X+121)^(1/2))/11) }
