Factoring a few special 4th degree polynomials
N^4 + N^2 + 1 = (N^2 - N + 1)(N^2 + N + 1) N^2 means N squared. N^4 means N reaised to the fourth power. N^4 + 2 N^2 + 9 = (N^2 - 2 N + 3) (N^2 + 2 N + 3) N^4 + 3 N^2 + 4 = (N^2 - N + 2) (N^2 + N + 2) N^4 + 4 N^2 + 4 = (N^2 + 2)^2 N^4 + 5 N^2 + 9 = (N^2 - N + 3) (N^2 + N + 3) N^4 + 6 N^2 + 9 = (N^2...
