Solution for (1/x^2)=11/19 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)

1/(x^2) = 11/19 // - 11/19

1/(x^2)-(11/19) = 0

1/(x^2)-11/19 = 0

1*x^-2 = 11/19 // : 1

x^-2 = 11/19

-2 < 0

1/(x^2) = 11/19 // * x^2

1 = 11/19*x^2 // : 11/19

19/11 = x^2

x^2 = 19/11 // ^ 1/2

abs(x) = (19/11)^(1/2)

x = (19/11)^(1/2) or x = -(19/11)^(1/2)

x in { (19/11)^(1/2), -(19/11)^(1/2) }
