(1/x-1)*(1/x+1) = 1 // - 1
(1/x-1)*(1/x+1)-1 = 0
(x^-1-1)*(x^-1+1)-1 = 0
(x^-1-1)*(x^-1+1)-1 = 0
x^-2-2 = 0
x^-2-2 = 0
1*x^-2 = 2 // : 1
x^-2 = 2
-2 < 0
1/(x^2) = 2 // * x^2
1 = 2*x^2 // : 2
1/2 = x^2
x^2 = 1/2 // ^ 1/2
abs(x) = (1/2)^(1/2)
x = (1/2)^(1/2) or x = -(1/2)^(1/2)
x in { (1/2)^(1/2), -(1/2)^(1/2) }
