Understanding the Remainder Theorem
The Remainder Theorem states that when a polynomial p(x) is divided by (x - a), the remainder is the value of the polynomial evaluated at x = a, which is p(a).
Let\'s consider your polynomial:
We want to find the remainder when p(x) is divided by (x - ). According to the Remainder Theorem, we need to calculate p():
Thus, the remainder is .
What is the Polynomial Remainder Theorem?
The Polynomial Remainder Theorem is a fundamental concept in algebra that simplifies finding the remainder of polynomial division. It states that if you divide a polynomial p(x) by a linear divisor (x - a), the remainder is simply p(a). For example, to find the remainder when p(x) = x² - 3x + 2 is divided by (x - 2), we evaluate p(2) = (2)² - 3(2) + 2 = 0. So, the remainder is 0. This theorem avoids long division, making it a quick way to find remainders and check factors of polynomials. It's widely used in polynomial factorization and root finding.
