((4*x-1)^2)/3 = 16 // - 16
((4*x-1)^2)/3-16 = 0
((4*x-1)^2)/3+(-16*3)/3 = 0
(4*x-1)^2-16*3 = 0
16*x^2-8*x-47 = 0
16*x^2-8*x-47 = 0
16*x^2-8*x-47 = 0
DELTA = (-8)^2-(-47*4*16)
DELTA = 3072
DELTA > 0
x = (3072^(1/2)+8)/(2*16) or x = (8-3072^(1/2))/(2*16)
x = (32*3^(1/2)+8)/32 or x = (8-32*3^(1/2))/32
