x in (-oo:+oo)
(9*x^2)/8-((53*x^1)/3)-6 = 0
(9*x^2)/8+(-53/3)*x-6 = 0
9/8*x^2-53/3*x-6 = 0
DELTA = (-53/3)^2-(-6*9/8*4)
DELTA = 3052/9
DELTA > 0
x = ((3052/9)^(1/2)+53/3)/(9/8*2) or x = (53/3-(3052/9)^(1/2))/(9/8*2)
x = 4/9*((3052/9)^(1/2)+53/3) or x = 4/9*(53/3-(3052/9)^(1/2))
x in { 4/9*(53/3-(3052/9)^(1/2)), 4/9*((3052/9)^(1/2)+53/3) }
