x in (-oo:+oo)
3*x^10-(((6*x^9)/9)*x^11) = 0
(-2/3)*x^20+3*x^10 = 0
3*x^10-2/3*x^20 = 0
t_1 = x^10
3*t_1^1-2/3*t_1^2 = 0
3*t_1-2/3*t_1^2 = 0
DELTA = 3^2-(-2/3*0*4)
DELTA = 9
DELTA > 0
t_1 = (9^(1/2)-3)/(-2/3*2) or t_1 = (-9^(1/2)-3)/(-2/3*2)
t_1 = 0 or t_1 = 9/2
t_1 = 0
x^10+0 = 0
x^10 = 0
1*x^10 = 0 // : 1
x^10 = 0
x = 0
t_1 = 9/2
x^10-9/2 = 0
1*x^10 = 9/2 // : 1
x^10 = 9/2
x^10 = 9/2 // ^ 1/10
abs(x) = (9/2)^(1/10)
x = (9/2)^(1/10) or x = -(9/2)^(1/10)
x in { 0, (9/2)^(1/10), -(9/2)^(1/10) }
