# PolynomialQuotientRemainder

PolynomialQuotientRemainder[p,q,x]

gives a list of the quotient and remainder of p and q, treated as polynomials in x.

# Details and Options

• The remainder will always have a degree not greater than q.

# Examples

open allclose all

## Basic Examples(2)

Find the quotient and remainder after dividing one polynomial by another:

The dividend is equal to the product of the quotient and the divisor plus the remainder:

Find the quotient and remainder for polynomials with symbolic coefficients:

## Scope(4)

The resulting polynomials will have coefficients that are rational expressions of input coefficients:

Polynomial quotient and remainder over the integers modulo :

Polynomial quotient and remainder over a finite field:

PolynomialQuotientRemainder also works for rational functions:

The quotient and remainder of division of by are and , where :

and are uniquely determined by the condition that the degree of is less than the degree of :

## Options(1)

### Modulus(1)

Use a prime modulus:
