Find the remainder when P(x) = 2x^3 + (-2)x + (3) is divided by x – (3).
Note
Apply the Remainder Theorem carefully. When a polynomial P(x) is divided by x - a, the remainder is P(a). Here the divisor is x - (3), so substitute x = 3 into the polynomial. P(3) = 2(3)^3 + (-2)(3) + (3) = 54 + -6 + 3 = 51. Therefore the remainder is 51.
