Find the roots of the equation f (x) = x3 - 0.2589x2 + 0.02262x - 0.001122 = 0

x1 = 0.16203454

x2 = 0.04843273+0.06766624j

x3 = 0.04843273-0.06766624j

Step-by-step explanation:

The better way to obtain roots of a polynomial when is not easy to analytically factorize is to use software as Matlab or Python. Use the following code in Python

import numpy as np

pol=np. array ([1,-0.2589, 0.02262,-0.001122])

roots=np. roots (pol)

print (roots)
