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)
48/(x^2)-36 = 0
48*x^-2 = 36 // : 48
x^-2 = 3/4
-2 < 0
1/(x^2) = 3/4 // * x^2
1 = 3/4*x^2 // : 3/4
4/3 = x^2
x^2 = 4/3 // ^ 1/2
abs(x) = (4/3)^(1/2)
x = (4/3)^(1/2) or x = -(4/3)^(1/2)
x in { (4/3)^(1/2), -(4/3)^(1/2) }
