A Polynomial Based Counting Puzzle

Algebra Level pending

Let w C w \in \mathbb{C} . We define A ( w ) A(w) to be the set of all non-constant polynomials P P such that the following properties hold:

  • If r r is a root of P P , then so is w r wr .
  • All roots of P P have a multiplicity of 1.
  • All roots of P P are non-zero.

Let Q 1 , Q 2 Q_1, Q_2 be polynomials of degree 8 and 12 respectively, where Q 1 Q_1 and Q 2 Q_2 do not share any roots. Determine the number of ordered triples ( w 1 , w 2 , w 3 ) (w_1, w_2, w_3) there are such that if Q 1 A ( w 1 ) Q_1 \in A(w_1) and Q 2 A ( w 2 ) Q_2 \in A(w_2) (provided such Q 1 , Q 2 Q_1, Q_2 exist) then Q 1 Q 2 A ( w 3 ) Q_1 Q_2 \in A(w_3) .


The answer is 231.
