Solution for 3X/(X^2-4X) equation: 


D( X )

X^2-(4*X) = 0

X^2-(4*X) = 0

X^2-(4*X) = 0

X^2-4*X = 0

X^2-4*X = 0

DELTA = (-4)^2-(0*1*4)

DELTA = 16

DELTA > 0

X = (16^(1/2)+4)/(1*2) or X = (4-16^(1/2))/(1*2)

X = 4 or X = 0

X in (-oo:0) U (0:4) U (4:+oo)

(3*X)/(X^2-(4*X)) = 0

(3*X)/(X^2-4*X) = 0

X^2-4*X = 0

X*(X-4) = 0

X-4 = 0 // + 4

X = 4

X*(X-4) = 0

(3*X)/(X*(X-4)) = 0

3*X = 0 // : 3

X = 0

X in { 0} 

X belongs to the empty set
