1; Given P(x) = (x - a)(x b)(x c) . lf P(-2) = P0) = O and P(3) = 10 , find all the zeroes of P(x). [4 marks] 2. The polynomial P(x) = 2):3 +6):2 + 5x3 leaves remainder ax + b when divided by (J:2 1). Use Remainder Theorem to nd the values of a and b. [5 marks] 3. The polynomial P(x) is defined by P(x) = 2x3 + mx2 + m: ._ 12 where m and n are constant. Given that (x + 4) is a factor of P(x) and 20 is the remainder when P(x) is divided by (x I) determine the values of m and n . t [6 marks]
