numpy.polyadd() : This function helps to find the sum of two polynomials and then returning the result as a polynomial. Each input polynomial must be a sequence of polynomial coefficients, from highest to lowest degree.
Parameters :
p1 : Input polynomial 1 p2 : Input polynomial 2
Return :
Sum of polynomials
# Python code explaining # numpy.polyadd ()   # importing libraries import numpy as np   p1 = np.poly1d([1, 2]) p2 = np.poly1d([9, 5, 4])   print ("P1 : ", p1) print ("\nP2 : \n", p2)   a = np.polyadd(p1, p2)   print ("\nP1 + P2 : \n", a) |
Output :
P1 :
1 x + 2
P2 :
2
9 x + 5 x + 4
P1 + P2 :
2
9 x + 6 x + 6
