D( x )
x = 0
x = 0
x = 0
x in (-oo:0) U (0:+oo)
x/2-(4/x) = x/3 // - x/3
x/2-(x/3)-(4/x) = 0
x/2-(x/3)-4*x^-1 = 0
1/6*x^1-4*x^-1 = 0
(1/6*x^2-4*x^0)/(x^1) = 0 // * x^2
x^1*(1/6*x^2-4*x^0) = 0
x^1
(1/6)*x^2-4 = 0
(1/6)*x^2-4 = 0
DELTA = 0^2-(-4*4*(1/6))
DELTA = 8/3
DELTA > 0
x = ((8/3)^(1/2)+0)/(2*(1/6)) or x = (0-(8/3)^(1/2))/(2*(1/6))
x = 3*(8/3)^(1/2) or x = 3*(8/3)^(1/2)
x in { 3*(8/3)^(1/2), 3*(8/3)^(1/2)}
x in { 3*(8/3)^(1/2), 3*(8/3)^(1/2) }
