This week I start complex numbers with my Precalculus class. This is a fun problem I found here (you can also go there for the solution when you’re ready).

This is a good problem, John. Another way to see the solution is to note that the polynomial x^2 + x + 1 is a factor of the polynomial x^3 – 1. Thus, all roots of the former are also roots of the latter. That is, any x that solves x^2 + x + 1 also solves x^3 = 1.

Happy birthday Mr.Chase!

wait…im confused.
