Solution for 2-(120/x^2) 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)

2-(120/(x^2)) = 0

2-120*x^-2 = 0

-120*x^-2 = -2 // : -120

x^-2 = 1/60

-2 < 0

1/(x^2) = 1/60 // * x^2

1 = 1/60*x^2 // : 1/60

60 = x^2

x^2 = 60 // ^ 1/2

abs(x) = 2*15^(1/2)

x = 2*15^(1/2) or x = -(2*15^(1/2))

x in { 2*15^(1/2), -(2*15^(1/2)) }
