Then
Now
and leave the same remainder when divided by
(and of course, as well).
(b) In any three consecutive integers, , one is always a multiple of . And and are primes, and neither nor is a multiple of
And, of course, is even whenever is a prime .
Hence
(c) Consider the remainders when (x-1) and (x+1) are divided by 3, and then use the results of (a).
