Sec 5.1, 10/4/09

-it makes sense how they relate the proof of corollary 5.5 to the corollary 2.5 about the integers but i am still confused on the proof. i am not being able to see how it works perfectly for polynomials.
-it is interesting to know how the concept of congruence and congruence classes arithmetic carry over from integers (Z) to F[x] with practically no change.
