m in (-oo:+oo)
(16*m^4)/3+(8*m^2)/3 = 0
16/3*m^4+8/3*m^2 = 0
t_1 = m^2
16/3*t_1^2+8/3*t_1^1 = 0
16/3*t_1^2+8/3*t_1 = 0
DELTA = (8/3)^2-(0*4*16/3)
DELTA = 64/9
DELTA > 0
t_1 = ((64/9)^(1/2)-8/3)/(2*16/3) or t_1 = (-(64/9)^(1/2)-8/3)/(2*16/3)
t_1 = 0 or t_1 = -1/2
t_1 = -1/2
m^2+1/2 = 0
1*m^2 = -1/2 // : 1
m^2 = -1/2
t_1 = 0
m^2+0 = 0
m^2 = 0
1*m^2 = 0 // : 1
m^2 = 0
m = 0
m = 0
