This is the sort of thing regression is good for. Dec18 comment Upper Triangular Form of a Matrix I would recommend reading the Wikipedia entry on Jordan Normal Form. Dec18 comment Find a pair of polynomials @AdenDong I'm glad my hint helped then :) Dec18 comment Find a pair of polynomials @AdenDong Good to know. You could also just let $r(x)=1$. Dec18 comment Find a pair of polynomials @AdenDong Glad to hear it! Did yours make use of the $r(x)$ polynomial? I was surprised that we didn't need it, and thought perhaps I had made a mistake. Dec18 answered Find a pair of polynomials Dec18 comment Find a pair of polynomials Here's what we know: $a^2=1-2a$ and $b^2=1-4b$, so any time we consider polynomials in $c$ we get some polynomial which we can always reduce to something with just $a$, $b$, and $ab$ (no higher powers).
