1. Problem Description

The problem asks us to find the remainder when the polynomial f(x)=2x313x2+14x+24f(x) = 2x^3 - 13x^2 + 14x + 24 is divided by (x3)(x-3).

2. Solution Steps

To find the remainder when f(x)f(x) is divided by (x3)(x-3), we can use the Remainder Theorem. The Remainder Theorem states that if a polynomial f(x)f(x) is divided by (xc)(x-c), then the remainder is f(c)f(c). In this case, we want to divide by (x3)(x-3), so c=3c = 3. We need to find f(3)f(3).
f(3)=2(3)313(3)2+14(3)+24f(3) = 2(3)^3 - 13(3)^2 + 14(3) + 24
f(3)=2(27)13(9)+14(3)+24f(3) = 2(27) - 13(9) + 14(3) + 24
f(3)=54117+42+24f(3) = 54 - 117 + 42 + 24
f(3)=54+42+24117f(3) = 54 + 42 + 24 - 117
f(3)=120117f(3) = 120 - 117
f(3)=3f(3) = 3

3. Final Answer

The remainder when f(x)f(x) is divided by (x3)(x-3) is 3.
