x in (-oo:+oo)
(5*x^2)/3-((44*x^1)/3)-9 = 0
(5*x^2)/3+(-44/3)*x-9 = 0
5/3*x^2-44/3*x-9 = 0
DELTA = (-44/3)^2-(-9*5/3*4)
DELTA = 2476/9
DELTA > 0
x = ((2476/9)^(1/2)+44/3)/(5/3*2) or x = (44/3-(2476/9)^(1/2))/(5/3*2)
x = 3/10*((2476/9)^(1/2)+44/3) or x = 3/10*(44/3-(2476/9)^(1/2))
x in { 3/10*(44/3-(2476/9)^(1/2)), 3/10*((2476/9)^(1/2)+44/3) }
