## How do you find the remainder of a polynomial?

Important Notes

1. When a polynomial a(x) is divided by a linear polynomial b(x) whose zero is x = k, the remainder is given by r = a(k)
2. The remainder theorem formula is: p(x) = (x-c)·q(x) + r(x).
3. The basic formula to check the division is: Dividend = (Divisor × Quotient) + Remainder.

## What is factor theorem calculator?

The factor theorem calculator provides step-wise calculations of the factor of division. Here you can understand how to find the remainder of a polynomial using the formula.

What is remainder formula?

Remainder Formula As we know, Dividend = Divisor × Quotient + Remainder. Accordingly, the remainder formula is given as: Remainder = Dividend – (Divisor × Quotient)

### How do you solve for a remainder?

Work the division in your calculator as normal. Once you have the answer in decimal form, subtract the whole number, then multiply the decimal value that’s left by the divisor of your original problem. The result is your remainder.

### What is divisor formula?

Divisor Formula Let us understand the formula of divisor when the remainder is 0, and when it is a non-zero number. If the remainder is 0, then Divisor = Dividend ÷ Quotient. If the remainder is not 0, then Divisor = (Dividend – Remainder)/ Quotient.

What is remainder theorem with example?

It is applied to factorize polynomials of each degree in an elegant manner. For example: if f(a) = a3-12a2-42 is divided by (a-3) then the quotient will be a2-9a-27 and the remainder is -123. Thus, it satisfies the remainder theorem.

## What is the remainder of 14 divided by 3?

2
14 divided by 3 gives quotient 4 and leaves a remainder 2.

## What do we use the polynomial remainder theorem for?

The Remainder Theorem is useful for evaluating polynomials at a given value of x , though it might not seem so, at least at first blush. This is because the tool is presented as a theorem with a proof, and you probably don’t feel ready for proofs at this stage in your studies.

What is the polynomial remainder theorem?

Polynomial remainder theorem. In algebra, the polynomial remainder theorem or little Bézout’s theorem (named after Étienne Bézout) is an application of Euclidean division of polynomials. It states that the remainder of the division of a polynomial f ( x ) {\\displaystyle f(x)} by a linear polynomial x − r {\\displaystyle x-r} is equal to f ( r ) .

### What are the long division steps?

There are four steps of long division; they are: divide, multiply, subtract, and bring down. Each step will be explained and shown in a different color in the step-by-step image. Our first step of long division is to divide.

### What is synthetic division and remainder theorem?

I introduce Synthetic Division and the Remainder Theorem. Synthetic division is a short cut to long division when you are dividing by a binomial in the form of (x-c). The Remainder Theorm is how you can use Synthetic Division to aid in evaluating polynomials at particular x values.
