x in (-oo:+oo)
(-2/4)*x^2-((-48/8)*x^4) = 0
6*x^4+(-2/4)*x^2 = 0
6*x^4-1/2*x^2 = 0
t_1 = x^2
6*t_1^2-1/2*t_1^1 = 0
6*t_1^2-1/2*t_1 = 0
DELTA = (-1/2)^2-(0*4*6)
DELTA = 1/4
DELTA > 0
t_1 = ((1/4)^(1/2)+1/2)/(2*6) or t_1 = (1/2-(1/4)^(1/2))/(2*6)
t_1 = 1/12 or t_1 = 0
t_1 = 0
x^2+0 = 0
x^2 = 0
1*x^2 = 0 // : 1
x^2 = 0
x = 0
t_1 = 1/12
x^2-1/12 = 0
1*x^2 = 1/12 // : 1
x^2 = 1/12
x^2 = 1/12 // ^ 1/2
abs(x) = (1/12)^(1/2)
x = (1/12)^(1/2) or x = -(1/12)^(1/2)
x in { 0, (1/12)^(1/2), -(1/12)^(1/2) }
