Solution for x^(-2)=1/6 equation: 


D( x )

x = 0

x = 0

x = 0

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

x^-2 = 1/6 // - 1/6

x^-2-(1/6) = 0

x^-2-1/6 = 0

1*x^-2 = 1/6 // : 1

x^-2 = 1/6

-2 < 0

1/(x^2) = 1/6 // * x^2

1 = 1/6*x^2 // : 1/6

6 = x^2

x^2 = 6 // ^ 1/2

abs(x) = 6^(1/2)

x = 6^(1/2) or x = -6^(1/2)

x in { 6^(1/2), -6^(1/2) }
