Solution for 1/12x^2-1/6x-1=0 equation: 


x in (-oo:+oo)

(1/12)*x^2-((1/6)*x)-1 = 0

(1/12)*x^2+(-1/6)*x-1 = 0

1/12*x^2-1/6*x-1 = 0

DELTA = (-1/6)^2-(-1*1/12*4)

DELTA = 13/36

DELTA > 0

x = ((13/36)^(1/2)+1/6)/(1/12*2) or x = (1/6-(13/36)^(1/2))/(1/12*2)

x = 6*((13/36)^(1/2)+1/6) or x = 6*(1/6-(13/36)^(1/2))

x in { 6*(1/6-(13/36)^(1/2)), 6*((13/36)^(1/2)+1/6) }
