I just had a generic question if im solving a 5th degree polynomial mod 11 and 12 i know i can just factor for 11 because its prime but for 12 do i check values 0-11 or 1-12? it seems like 0 would be trivial.

The numbers (aka classes) mod 12 are 0-11. So yes you can use 0, and yes, it is often trivial.
