Solution for 4/x^2-12=1 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)

4/(x^2)-12 = 1 // - 1

4/(x^2)-12-1 = 0

4*x^-2 = 13 // : 4

x^-2 = 13/4

-2 < 0

1/(x^2) = 13/4 // * x^2

1 = 13/4*x^2 // : 13/4

4/13 = x^2

x^2 = 4/13 // ^ 1/2

abs(x) = (4/13)^(1/2)

x = (4/13)^(1/2) or x = -(4/13)^(1/2)

x in { (4/13)^(1/2), -(4/13)^(1/2) }
