Solution for (2*10^-6/x^2)=18*10^-6 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*10^-6)/(x^2) = 18*10^-6 // - 18*10^-6

(2*10^-6)/(x^2)-(18*10^-6) = 0

(2*10^-6)/(x^2)-18*10^-6 = 0

1/500000*x^-2 = 9/500000 // : 1/500000

x^-2 = 9

-2 < 0

1/(x^2) = 9 // * x^2

1 = 9*x^2 // : 9

1/9 = x^2

x^2 = 1/9 // ^ 1/2

abs(x) = 1/3

x = 1/3 or x = -1/3

x in { 1/3, -1/3 }
