x in (-oo:+oo)
24*x^2-(x*((40*x^3)/8)) = 0
24*x^2-5*x^4 = 0
t_1 = x^2
24*t_1^1-5*t_1^2 = 0
24*t_1-5*t_1^2 = 0
DELTA = 24^2-(-5*0*4)
DELTA = 576
DELTA > 0
t_1 = (576^(1/2)-24)/(-5*2) or t_1 = (-576^(1/2)-24)/(-5*2)
t_1 = 0 or t_1 = 24/5
t_1 = 0
x^2+0 = 0
x^2 = 0
1*x^2 = 0 // : 1
x^2 = 0
x = 0
t_1 = 24/5
x^2-24/5 = 0
1*x^2 = 24/5 // : 1
x^2 = 24/5
x^2 = 24/5 // ^ 1/2
abs(x) = (24/5)^(1/2)
x = (24/5)^(1/2) or x = -(24/5)^(1/2)
x in { 0, (24/5)^(1/2), -(24/5)^(1/2) }
