Solution for 0=0.1-(28900/(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)

0 = 0.1-(28900/(x^2)) // - 0.1-(28900/(x^2))

28900/(x^2)-0.1+0 = 0

28900/(x^2)-0.1 = 0

28900*x^-2 = 0.1 // : 28900

x^-2 = 0.00000346

-2 < 0

1/(x^2) = 0.00000346 // * x^2

1 = 0.00000346*x^2 // : 0.00000346

289017.34104046 = x^2

x^2 = 289017.34104046 // ^ 1/2

abs(x) = 289017.34104046^(1/2)

x = 289017.34104046^(1/2) or x = -289017.34104046^(1/2)

x in { 289017.34104046^(1/2), -289017.34104046^(1/2) }
