Q. The polynomial function f is defined as f(c)=(c−k)(c2−4c+4) where k is a constant. The value 2 is a zero of f. What is the remainder of f(c) when divided by (c−2)?◻
Identify Given Information: Identify the given information and the question prompt.We are given that f(c)=(c−k)(c2−4c+4) and that 2 is a zero of f. We need to find the remainder when f(c) is divided by (c−2).
Determine Value of k: Use the fact that 2 is a zero of f to determine the value of k. If 2 is a zero of f, then f(2)=0. We can substitute c with 2 in the equation f(c)=(c−k)(c2−4c+4) to find k. f0
Apply Remainder Theorem: Simplify the equation to find k.f(2)=(2−k)(4−8+4)=(2−k)(0)=0Since (2−k)(0)=0 for any value of k, we cannot determine k from this equation. However, we do not need the value of k to find the remainder when f(c) is divided by (c−2).
Substitute to Find Remainder: Apply the Remainder Theorem to find the remainder.The Remainder Theorem states that the remainder of a polynomial f(c) when divided by (c−a) is f(a). Since we want to divide f(c) by (c−2), we need to find f(2).
Calculate Remainder: Substitute c with 2 in the polynomial f(c) to find the remainder.f(2)=(2−k)(22−4⋅2+4)Simplify the expression.f(2)=(2−k)(4−8+4)=(2−k)(0)
Calculate Remainder: Substitute c with 2 in the polynomial f(c) to find the remainder.f(2)=(2−k)(22−4⋅2+4)Simplify the expression.f(2)=(2−k)(4−8+4)=(2−k)(0)Calculate the remainder.f(2)=(2−k)(0)=0The remainder of f(c) when divided by (c−2) is 0.
