Hello @SEJPM
I have a question

According to my notes:

I haven't understood the observation that such a conclusion cannot be drawn for polynomials $f_1, f_2$ that are not in P.

Do you have an idea why this holds? :/ @SEJPM

@Evinda I don't but want to note that the intuition behind P seems to be "all polynomials which as 'primes-factors' use only (X+a) with a in the given range"
