Math Problem Statement

If f(x) = x^6 - 4x - 4, then what is the remainder when f(x) is divided by x - 1?

Solution

To solve this problem, we need to use the Remainder Theorem, which states that if a polynomial f(x)f(x) is divided by xax - a, the remainder is f(a)f(a).

Given: f(x)=x64x4f(x) = x^6 - 4x - 4 We need to find the remainder when f(x)f(x) is divided by x1x - 1. According to the Remainder Theorem, the remainder is f(1)f(1).

Let's calculate f(1)f(1):

f(1)=(1)64(1)4=144=7f(1) = (1)^6 - 4(1) - 4 = 1 - 4 - 4 = -7

So, the remainder when f(x)f(x) is divided by x1x - 1 is -7.

  1. What is the Remainder Theorem, and how is it used in polynomial division?
  2. Can we use synthetic division to verify the remainder when dividing f(x)f(x) by x1x - 1?
  3. How would the remainder change if f(x)f(x) were divided by x2x - 2?
  4. What does the Remainder Theorem tell us about the relationship between roots and remainders?
  5. How can the Remainder Theorem be applied to higher-degree polynomials?

Tip: When applying the Remainder Theorem, always evaluate the polynomial at aa for xax - a, which quickly gives you the remainder without doing the full division.
