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)
y = 10/(x^2) // - 10/(x^2)
y-(10/(x^2)) = 0
y-10*x^-2 = 0
-10*x^-2 = -y // : -10
x^-2 = y/10
-2 < 0
1/(x^2) = y/10 // * x^2
1 = x^2*(y/10) // : y/10
10*y^-1 = x^2
x^2 = 10*y^-1 // ^ 1/2
abs(x) = 10^(1/2)*y^(-1/2)
x = 10^(1/2)*y^(-1/2) or x = -(10^(1/2)*y^(-1/2))
x in { 10^(1/2)*y^(-1/2), -(10^(1/2)*y^(-1/2)) }
