If a polynomial is divided by x - c, we can use the Remainder theorem to evaluate the polynomial at c.
The Remainder theorem:
If the polynomial f(x) is divided by x - c, then the remainder is f(c).
Example:
Given f(x) = x^3 - 4x^2 + 5x + 3, use the remainder theorem to find f(2).
Solution:
By the remainder theorem, if f(x) is divided by x - 2, then the remainder is f(2).
We can use the synthetic division to divide.
2] 1 -4 5 3
2 -4 2
__________
1 -2 1 5
The remainder is 5, so f(2) = 5
Check:
f(x) = x^3 - 4x^2 + 5x + 3
f(2) = (2)^3 - 4(2)^2 + 5(2) + 3 = 8 - 16 + 10 + 3 = 5

What is polynomial division?
That means that you divide one polynomial by another polynomial. Basically, if you have polynomials "A" and "B", you look for a polynomial "C" and a remainder "R", such that: B x C + R = A ... such that the remainder has a lower degree than polynomial "B", the polynomial by which you are dividing. For example, if you divide by a polynomial of degree 3, the remainder must be of degree 2 or less.
If a polynomial is divided by (x-a) and the remainder equals zero then (x-a) is a factor of the polynomial?

What is the polynomial factor theorem?
Suppose p(x) is a polynomial in x. Then p(a) = 0 if and only if (x-a) is a factor of p(x).
Is it false if a polynomial is divided by (x-a) and the remainder equals zero then (x-a) is a factor of the polynomial?
No, it’s true. It’s the same as saying if 60 is divided by 2 and the remainder equals zero (no remainder, so it divides perfectly), 2 is a factor of 60.
What is the remainder when 3 is synthetically divided into the polynomial -2x2 7x-9?
-6
Who discovered the polynomial remainder theorem?
Euclid

How can you tell if a binomial divides evenly into a polynomial?
Do the division, and see if there is a remainder.
According to the Remainder theorem the remainder of the problem in which a polynomial F x is divided by the binomial x - a equals?
F(a)
What is the remainder thereom?
The remainder theorem states that if you divide a polynomial function by one of it's linier factors it's degree will be decreased by one. This theorem is often used to find the imaginary zeros of polynomial functions by reducing them to quadratics at which point they can be solved by using the quadratic formula.
What is the use of remainder and factor theorem in your daily life?

How do you solve a remainder theorem?
You cannot solve a theorem: you can prove the theorem or you can solve a question based on the remainder theorem.
What are Questions for remainders?
The answer depends on the level of mathematics you are at: from simple remainders left when one number is divided by another to the remainder theorem where is is the division of one polynomial by another.

Why 4 is used in remainder theorem?
Any rational number can be used in the remainder theorem: 4 does not have a special role.
