The main objective here is D’Alembert’s Theorem: a polynomial of degree . with coefficients in a field can have no more than . roots in the field. D’Alembert’s Theorem will become highly useful for explaining Ree

Institutions for Water Management in Mexico, method, for pairwise coprime moduli, uses Bezout’s Identity and yields the Chinese Remainder Theorem. An immediate application of this case is to speed up the decryption of messages in an RSA cryptosystem. For the general case of systems of congruences to non-coprime moduli, we show how to decide i
