prime producing polynomial
See this polynomial
f(n) = n^2 + n + 41 assume n is a positive integer I once received a standing ovation for a presentation on this topic at a 3 day math conference. It was at Salishan Oregon USA, at a conference for community college math teachers. I have done some community college math teaching. I hope you find this interesting.

Here is a list of many algebraic factorization s to find cases when
f(n) = n^2 + n + 41 is a composite number. I used a data table from a Maple calculation to list numbers when f(n) is a composite number. Then I used the method of 3 point quadratic curve fit to list parabolas. The parabolas are parametric and for all integers on these parabolic curves, f(n) is a composite number. (There are no graphs in this file.) look Matt Last fiddled with by MattcAnderson on 2021-06-16 at 13:35 Reason: explained method |
