D( t )
t = 0
t = 0
t = 0
t in (-oo:0) U (0:+oo)
24/t-t = 5 // - 5
24/t-t-5 = 0
24*t^-1-1*t^1-5*t^0 = 0
(24*t^0-1*t^2-5*t^1)/(t^1) = 0 // * t^2
t^1*(24*t^0-1*t^2-5*t^1) = 0
t^1
24-t^2-5*t = 0
24-t^2-5*t = 0
DELTA = (-5)^2-(-1*4*24)
DELTA = 121
DELTA > 0
t = (121^(1/2)+5)/(-1*2) or t = (5-121^(1/2))/(-1*2)
t = -8 or t = 3
t in { -8, 3}
