Question

the degree of constant polynomial is (a) 3 (b)2 (c)1 (d) 0

Answer 1

the degree of constant polynomial is Zero. and it is known as zero polynomial

Answer 2

The degree of the zero polynomial is either left undefined, or is defined to be negative (usually −1 or ). Like any constant value, the value 0 can be considered as a (constant) polynomial, called the zero polynomial. It has no non zero terms, and so, strictly speaking, it has no degree either. So the answer is (d).
