a) Evaluate each of p, q, r at 0 and 1.
b) Compute pr, q^2 and q(p-r)
c) Find the quotient and remainder on dividing p by q.
Do you understand that (a) is just integer arithmetic? (b) is not much harder. (c) could be hard but there are several different ways to do it. What methods of polynomial division have you learned?
