Solution for 1/x^2=10/15 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) = 10/15 // - 10/15

1/(x^2)-(10/15) = 0

1/(x^2)-2/3 = 0

1*x^-2 = 2/3 // : 1

x^-2 = 2/3

-2 < 0

1/(x^2) = 2/3 // * x^2

1 = 2/3*x^2 // : 2/3

3/2 = x^2

x^2 = 3/2 // ^ 1/2

abs(x) = (3/2)^(1/2)

x = (3/2)^(1/2) or x = -(3/2)^(1/2)

x in { (3/2)^(1/2), -(3/2)^(1/2) }
