((3*x-2)^2)/3 = 16 // - 16
((3*x-2)^2)/3-16 = 0
((3*x-2)^2)/3+(-16*3)/3 = 0
(3*x-2)^2-16*3 = 0
9*x^2-12*x-44 = 0
9*x^2-12*x-44 = 0
9*x^2-12*x-44 = 0
DELTA = (-12)^2-(-44*4*9)
DELTA = 1728
DELTA > 0
x = (1728^(1/2)+12)/(2*9) or x = (12-1728^(1/2))/(2*9)
x = (24*3^(1/2)+12)/18 or x = (12-24*3^(1/2))/18
