Q16) A and B
(a) When a polynomial is divided by (2x+1)(x-3), the remainder is 3x-1. What is the remainder when the polynomial is divided by 2x+1?
(b) When x^5 + 3x^3 + ax + b is divided by x^2 - 1, the remainder is 2x - 7. Find a and b.
(c) When a polynomial P(x) is divided by x^2 - 5, the remainder is x + 4. Find the remainder when P(x) + P(-x) is divided by x^2 - 5. (Hint: Write down the division identity.)
Please help I am stuck, thank you
