x in (-oo:+oo)
(6*x^2)/3-((47*x^1)/3)-8 = 0
(6*x^2)/3+(-47/3)*x-8 = 0
2*x^2-47/3*x-8 = 0
DELTA = (-47/3)^2-(-8*2*4)
DELTA = 2785/9
DELTA > 0
x = ((2785/9)^(1/2)+47/3)/(2*2) or x = (47/3-(2785/9)^(1/2))/(2*2)
x = ((2785/9)^(1/2)+47/3)/4 or x = (47/3-(2785/9)^(1/2))/4
x in { (47/3-(2785/9)^(1/2))/4, ((2785/9)^(1/2)+47/3)/4 }
