Hi I have another problem..Two polynomials a(x) and b(x) are asociated iff a(x)|b(x) and b(x)|a(x)….Right? And now my problem..And polynomials are indivisible when gcd is asociated with 1..And there it is..In which universe is it for example 2??As I know 1 is indivisible by 2?Is there something I am overlooking? yes and all of this in any field e.g. $Z_3[x]$
Oh sorry I forget to specify which I am asking for:) So..I know that polynomials e.g. in $Z_3[x]$ are indivisible iff gcd is 1 or 2??And I am asking why?I know that 1 and 2 has to be mutually asociated..But I dont know why..I understand why these polynomials are indivisible, but I dont know why this asociation is valid..
