Solution for (18x^2-12x-3)/3 equation: 


x in (-oo:+oo)

(18*x^2-(12*x)-3)/3 = 0

(18*x^2-12*x-3)/3 = 0

18*x^2-12*x-3 = 0

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

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

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

DELTA = 40

DELTA > 0

x = (40^(1/2)+4)/(2*6) or x = (4-40^(1/2))/(2*6)

x = (2*10^(1/2)+4)/12 or x = (4-2*10^(1/2))/12

3*(x-((4-2*10^(1/2))/12))*(x-((2*10^(1/2)+4)/12)) = 0

(x-((4-2*10^(1/2))/12))*(x-((2*10^(1/2)+4)/12)) = 0

( x-((2*10^(1/2)+4)/12) )

x-((2*10^(1/2)+4)/12) = 0 // + (2*10^(1/2)+4)/12

x = (2*10^(1/2)+4)/12

( x-((4-2*10^(1/2))/12) )

x-((4-2*10^(1/2))/12) = 0 // + (4-2*10^(1/2))/12

x = (4-2*10^(1/2))/12

x in { (2*10^(1/2)+4)/12, (4-2*10^(1/2))/12 }
