Question A2: When we study case analysis, we will consider the polynomial function p(n) = 2n³ + 3n²+ n. We know from the first week of class that p(n): : 12 +2²+.... + n², and this gives the remarkable fact that the following implication is true: If n is an integer, then 2n³ +3n² +n is a multiple of 6. We will use case analysis, in clase, to verify this fact directly. It is helpful to note that p(n) can be written as a product, since 2n³ +3n² + n = (2n + 1)(n+1)(n). (a) How can you check that the factorization given above is true?
