    If you take both sides to the 1/6 power, you get x+2=2^2; x=2. Thereafter, you could expand the expression on the left using Pascal’s triangle, and divide using synthetic division to get the other roots.

    We could reject the complex answers. Simply make it (x + 2) = +/- 4. So x = 2, -6.

    Use 1^x to denote exp(2πix) = cos 2πx + i sin 2πx. Lemma: the solutions to x⁶ = 1 are x = 1^{n/6} for n = 0, 1, 2, 3, 4, 5. Proof: at most 6 solutions to a 6th degree polynomial equation can exist. Each of the proposed solutions checks out (just multiply their exponents by 6), and there are 6 of them. Therefore they are all of the solutions. QED. (x + 2)⁶ = 2¹² (= 4⁶) if and only if ((x + 2)/4)⁶ = 1 if and only if (x + 2)/4 = 1^{n/6} for n = 0, 1, 2, 3, 4, 5 (by the lemma), if and only if x = -2 + 4·1^{n/6}, for n = 0, 1, 2, 3, 4, 5. Those are your 6 solutions. In more prosaic and familiar terms: x = -2 + 4(cos πn/3 + i sin πn/3), for n = 0, 1, 2, 3, 4, 5. By the way: x⁶ - 1 = (x - 1^0) (x - 1^⅙) (x - 1^⅓) (x - 1^½) (x - 1^⅔) (x - 1^⅚) = C₁(x) C₂(x) C₃(x) C₆(x), where: C₁(x) = (x - 1^0) = x - 1, C₂(x) = (x - 1^½) = x + 1, C₃(x) = (x - 1^⅓) (x - 1^⅔) = x² + x + 1, C₆(x) = (x - 1^⅙) (x - 1^⅚) = x² - x + 1.
