- P is a polynomial. When P is divided by x − 1, the remainder is − 4. When P is divided by x − 2, the remainder is − 1. When P is divided by x − 3, the remainder is 4. 3 2 Determine the remainder when P is divided by x − 6 x + 11 x − 6. Solution: The remainder polynomial is simply the order two polynomial that goes 2 through the points (1 , − 4), (2 , − 1), and (3 , 4): x − 5 . π π 4 2 1
