Question

PLEASE USE PYTHON CODE

11. Find all zeros of given P_n(x)

P₅(x) = x^5 -156x^4 -5x^3 +780x^2 + 4x - 624

Answer 1

Hey, This can be done easily with Numpy.

import numpy as np

p = np.poly1d([1, -156, -5,780,4,-624]) 
#we define polynomial by passing it's coefficients in poly1d function which is inbuilt in numpy. 

print(p) #Now, I have printed the polynomial just to check if the polynomial is right or not.

root=p.r #Now finding roots of the polynomial and storing it in root variable.

print(root) #Now print root
