Question

Degree of which of the following polynomials is zero:

• A. x
• B. 15
• C. y
• D. $x+x^2$

Answer 1

The correct option is B 15

The degree of a polynomial is the highest degree of its monomials (individual terms) with non-zero coefficients. The degree of a term is the sum of the exponents of the variables that appear in it, and thus is a non-negative integer.

For, non-zero constants, degree is zero.

Here, $15$ is the only non-zero constant and thus has zero degree.

Hence, $B$ is correct.
