x in (-oo:+oo)
(4*x^2)/3-((11*x^1)/3)-3 = 0
(4*x^2)/3+(-11/3)*x-3 = 0
4/3*x^2-11/3*x-3 = 0
DELTA = (-11/3)^2-(-3*4/3*4)
DELTA = 265/9
DELTA > 0
x = ((265/9)^(1/2)+11/3)/(4/3*2) or x = (11/3-(265/9)^(1/2))/(4/3*2)
x = 3/8*((265/9)^(1/2)+11/3) or x = 3/8*(11/3-(265/9)^(1/2))
x in { 3/8*(11/3-(265/9)^(1/2)), 3/8*((265/9)^(1/2)+11/3) }
