The remainder theorem is used to find the remainder without using the long division when a polynomial is divided by a linear polynomial. It says when a polynomial p(x) is divided by (x - a) then the remainder is p(a).

The Polynomial Remainder Theorem allows us to determine whether a linear expression is a factor of a polynomial expression easily. It tells us the remainder when a polynomial is divided by \[x - a\] is \[f(a)\]. This means if \[x - a\] is a factor of the polynomial, the remainder is zero.
Apply the remainder theorem step by step. The calculator will calculate f(a) f ( a) using the remainder (little Bézout's) theorem, with steps shown.
The Remainder Theorem. When we divide f (x) by the simple polynomial x−c we get: f (x) = (x−c) q (x) + r (x) x−c is degree 1, so r (x) must have degree 0, so it is just some constant r: f (x) = (x−c) q (x) + r. Now see what happens when we have x equal to c: f (c) = (c−c) q (c) + r. f (c) = (0) q (c) + r. f (c) = r. So we get this:
The Polynomial Remainder Theorem simplifies the process of finding the remainder when dividing a polynomial by \[x - a\]. Instead of long division, you just evaluate the polynomial at \[a\]. This method saves time and space, making polynomial division more manageable.
Remainder theorem: checking factors. Learn how to determine if an expression is a factor of a polynomial by dividing the polynomial by the expression. If the remainder is zero, the expression is a factor. The video also demonstrates how to quickly calculate the remainder using the theorem.
Remainder Theorem is an approach of Euclidean division of polynomials. According to this theorem, if we divide a polynomial P (x) by a factor ( x – a); that isn’t essentially an element of the polynomial; you will find a smaller polynomial along with a remainder.
