Solution for t^2-4/6t-12 equation: 


t in (-oo:+oo)

t^2-((4/6)*t)-12 = 0

t^2+(-2/3)*t-12 = 0

t^2-2/3*t-12 = 0

DELTA = (-2/3)^2-(-12*1*4)

DELTA = 436/9

DELTA > 0

t = ((436/9)^(1/2)+2/3)/(1*2) or t = (2/3-(436/9)^(1/2))/(1*2)

t = ((436/9)^(1/2)+2/3)/2 or t = (2/3-(436/9)^(1/2))/2

t in { (2/3-(436/9)^(1/2))/2, ((436/9)^(1/2)+2/3)/2 }
