We'll argue by induction on the number of irreducible factors of q. If q = d1 then we can just use polynomial long division to get a b1 with p = a0d1 + b0, or rather p q = a0 + b0 d1. Now we'll move to the induction step.
WebDec 7, 2014 · Partial fraction decomposition in this setting describes the additive group of the field of fractions of a principal ideal domain using essentially the Chinese remainder theorem, but that's a story for another day...
