For example, in the chromatic polynomial of our five-node loop, P(q) =q 5 – 5q 4 + 10q 3 – 10q 2 + 4q, we see that 5 2 ≥ 1 × 10, 10 2 ≥ 5 × 10 and 10 2 ≥ 10 × 4. One thing this shows is that not every ...

Roots of unity are the roots of the polynomials of the form x n – 1. For example, when n = 2, this gives us the quadratic polynomial x 2 – 1. To find its roots, just set it equal to 0 and solve: x 2 – ...
