Details:

For computation with imaginary
Let a = 1 angle 120 degrees

a = (cosd(120) + ((sind(120)*i)))
a = -0.50000 + 0.86603i

(a^2) + a + 1
ans = 0.0000e+000 + 3.3307e-016i

1 + a + (a^2)
ans = -1.1102e-016 + 3.3307e-016i

a + 1 + (a^2)
ans = -1.1102e-016 + 3.3307e-016i

I thought it would give me same answers of 0 + 0i?

Thank you, I am using windows 10 OS.
