Solution for 6x^2-12x-3x^2=2/18 equation: 


x in (-oo:+oo)

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

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

6*x^2-3*x^2-12*x-1/9 = 0

3*x^2-12*x-1/9 = 0

DELTA = (-12)^2-(-1/9*3*4)

DELTA = 436/3

DELTA > 0

x = ((436/3)^(1/2)+12)/(2*3) or x = (12-(436/3)^(1/2))/(2*3)

x = ((436/3)^(1/2)+12)/6 or x = (12-(436/3)^(1/2))/6

x in { (12-(436/3)^(1/2))/6, ((436/3)^(1/2)+12)/6 }
