Solution for X-4/2X+3X/2X-1 equation: 


X in (-oo:+oo)

((3*X)/2)*X+X-((4/2)*X)-1 = 0

((3*X)/2)*X+X-2*X-1 = 0

3/2*X^2-X-1 = 0

DELTA = (-1)^2-(-1*3/2*4)

DELTA = 7

DELTA > 0

X = (7^(1/2)+1)/(3/2*2) or X = (1-7^(1/2))/(3/2*2)

X = (7^(1/2)+1)/3 or X = (1-7^(1/2))/3

X in { (1-7^(1/2))/3, (7^(1/2)+1)/3 }
