x in (-oo:+oo)
6*x^8-(x*((10*x^3)/2)) = 0
6*x^8-5*x^4 = 0
t_1 = x^4
6*t_1^2-5*t_1^1 = 0
6*t_1^2-5*t_1 = 0
DELTA = (-5)^2-(0*4*6)
DELTA = 25
DELTA > 0
t_1 = (25^(1/2)+5)/(2*6) or t_1 = (5-25^(1/2))/(2*6)
t_1 = 5/6 or t_1 = 0
t_1 = 0
x^4+0 = 0
x^4 = 0
1*x^4 = 0 // : 1
x^4 = 0
x = 0
t_1 = 5/6
x^4-5/6 = 0
1*x^4 = 5/6 // : 1
x^4 = 5/6
x^4 = 5/6 // ^ 1/4
abs(x) = (5/6)^(1/4)
x = (5/6)^(1/4) or x = -(5/6)^(1/4)
x in { 0, (5/6)^(1/4), -(5/6)^(1/4) }
