Let \(z\) be a complex number such that \(z^5 + z^4 + 2z^3 + z^2 + z = 0\)
Find all possible values of \(|z|\)

List all possible values, separated by commas.

The equation factors as z(z^2 + z + 1)^2 = 0, so the solutions are $0, -\frac{1}{2} + \frac{\sqrt{3}}{2} i, -\frac{1}{2} - \frac{\sqrt{3}}{2} i$.
