Appendix to Chapter 21

The divisibility of polynomials  to G(x) = x^3+Bx^2+Cx-D was derived in Chapter 21.  In this appendix the divisibility is extended to conjugates of G(x) and other higher degree polynomials.   A general conjecture is made regarding all cubic irreducible polynomials of negative discriminant.
