x in (-oo:+oo)
32*x-(16*x^2)+1/(-12) = 0
32*x-16*x^2+1/(-12) = 0
32*x-16*x^2-1/12 = 0
DELTA = 32^2-(-16*(-1/12)*4)
DELTA = 1024-16/3
DELTA = 3056/3
DELTA > 0
x = ((1024-16/3)^(1/2)-32)/(-16*2) or x = (-(1024-16/3)^(1/2)-32)/(-16*2)
x = ((1024-16/3)^(1/2)-32)/(-32) or x = ((1024-16/3)^(1/2)+32)/32
x in { ((1024-16/3)^(1/2)-32)/(-32), ((1024-16/3)^(1/2)+32)/32 }
