Answer:
Option (d) is correct.
The given polynomial is a prime polynomial.
Step-by-step explanation:
Given :
We have to factorize it completely.
Since , factorization is the process of reducing a given polynomial into a lower degree polynomial by taking common factors out into the simplest form.
Consider the given polynomial
Since the given polynomial do not have any term common in both terms .
So we cannot factorized it further.
So, the given polynomial is a prime polynomial.
Thus, Option (d) is correct.
