Answer:
Option (b) is correct.
Given polynomial
is 4th degree polynomial.
Explanation:
Given polynomial

We have to choose the correct classification of given polynomial out of given option .
Degree of polynomial is the highest degree of polynomial having non zero coefficient.
5th degree polynomial is the polynomial having highest degree of variable is 5 with non zero coefficient.
4th degree polynomial is the polynomial having highest degree of variable is 4 with non zero coefficient.
9th degree polynomial is the polynomial having highest degree of variable is 9 with non zero coefficient.
24th degree polynomial is the polynomial having highest degree of variable is 24 with non zero coefficient.
Thus, for the given polynomial
the highest degree is 3 of term
with non zero coefficient 3.
Thus, Given polynomial
is 4th degree polynomial.
Option (b) is correct.
