Divide one polynomial by another in Python

To divide one polynomial by another, use the numpy.polynomial.polynomial.polydiv() method in Python. Returns the quotient-with-remainder of two polynomials c1 / c2. The arguments are sequences of coefficients, from lowest order term to highest, e.g., [1,2,3] represents 1 + 2*x + 3*x**2.

The method returns the array of coefficient series representing the quotient and remainder. The parameters c1 and c2 are the 1-D arrays of coefficients representing a polynomial, relative to the “standard” basis, and ordered from lowest order term to highest.

This numpy.polynomial.polynomial module provides a number of objects useful for dealing with polynomials, including a Polynomial class that encapsulates the usual arithmetic operations.

Steps

At first, import the required libraries −

from numpy.polynomial import polynomial as P

Declare Two Polynomials −

p1 = (4,1,6) p2 = (2,5,3)

Display the polynomials −

print("Polynomial 1...\n",p1) print("\nPolynomial 2...\n",p2)

To divide one polynomial by another, use the numpy.polynomial.polynomial.polydiv() method in Python −

mulRes = P.polydiv(p1,p2); print("\nResult (divide)...\n",mulRes)

Example

from numpy.polynomial import polynomial as P # Declare Two Polynomials p1 = (4,1,6) p2 = (2,5,3) # Display the polynomials print("Polynomial 1...\n",p1) print("\nPolynomial 2...\n",p2) # To divide one polynomial by another, use the numpy.polynomial.polynomial.polydiv() method in Python. mulRes = P.polydiv(p1,p2); print("\nResult (divide)...\n",mulRes)

Output

Polynomial 1... (4, 1, 6) Polynomial 2... (2, 5, 3) Result (divide)... (array([2.]), array([ 0., -9.]))
