x in (-oo:+oo)
(3*x^2)/3-((23*x^1)/3)-8 = 0
(3*x^2)/3+(-23/3)*x-8 = 0
x^2-23/3*x-8 = 0
DELTA = (-23/3)^2-(-8*1*4)
DELTA = 817/9
DELTA > 0
x = ((817/9)^(1/2)+23/3)/(1*2) or x = (23/3-(817/9)^(1/2))/(1*2)
x = ((817/9)^(1/2)+23/3)/2 or x = (23/3-(817/9)^(1/2))/2
x in { (23/3-(817/9)^(1/2))/2, ((817/9)^(1/2)+23/3)/2 }
