Solution for 2/3x^2-1/6x-4=0 equation: 


x in (-oo:+oo)

(2/3)*x^2-((1/6)*x)-4 = 0

(2/3)*x^2+(-1/6)*x-4 = 0

2/3*x^2-1/6*x-4 = 0

DELTA = (-1/6)^2-(-4*2/3*4)

DELTA = 385/36

DELTA > 0

x = ((385/36)^(1/2)+1/6)/(2/3*2) or x = (1/6-(385/36)^(1/2))/(2/3*2)

x = 3/4*((385/36)^(1/2)+1/6) or x = 3/4*(1/6-(385/36)^(1/2))

x in { 3/4*(1/6-(385/36)^(1/2)), 3/4*((385/36)^(1/2)+1/6) }
