Solution for 8a^2/6a^2-4a^2 equation: 


a in (-oo:+oo)

((8*a^2)/6)*a^2-(4*a^2) = 0

((8*a^2)/6)*a^2-4*a^2 = 0

4/3*a^4-4*a^2 = 0

t_1 = a^2

4/3*t_1^2-4*t_1^1 = 0

4/3*t_1^2-4*t_1 = 0

DELTA = (-4)^2-(0*4/3*4)

DELTA = 16

DELTA > 0

t_1 = (16^(1/2)+4)/(4/3*2) or t_1 = (4-16^(1/2))/(4/3*2)

t_1 = 3 or t_1 = 0

t_1 = 0

a^2+0 = 0

a^2 = 0

1*a^2 = 0 // : 1

a^2 = 0

a = 0

t_1 = 3

a^2-3 = 0

1*a^2 = 3 // : 1

a^2 = 3

a^2 = 3 // ^ 1/2

abs(a) = 3^(1/2)

a = 3^(1/2) or a = -3^(1/2)

a in { 0, 3^(1/2), -3^(1/2) }
