Solution for 0=(-4/x^(2))+0,001X+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)

0 = 0.001*X-4/(x^2)+2 // - 0.001*X-4/(x^2)+2

0-(0.001*X)-(-4/(x^2))-2 = 0

4*x^-2-0.001*X-2 = 0

4*x^-2 = -(-0.001*X-2) // : 4

x^-2 = (2-(-0.001*X))/4

-2 < 0

1/(x^2) = (2-(-0.001*X))/4 // * x^2

1 = x^2*((2-(-0.001*X))/4) // : (2-(-0.001*X))/4

4*(0.001*X+2)^-1 = x^2

x^2 = 4*(0.001*X+2)^-1 // ^ 1/2

abs(x) = 2*(0.001*X+2)^(-1/2)

x = 2*(0.001*X+2)^(-1/2) or x = -(2*(0.001*X+2)^(-1/2))

x in { 2*(0.001*X+2)^(-1/2), -(2*(0.001*X+2)^(-1/2)) }
