Question

What is the degree of a non-zero constant polynomial?

Answer 1

If $P\left(x\right)$ is the polynomial then The degree of $P\left(x\right)$ is the highest or greatest power of a variable.

The degree of non-zero constant polynomial is $0$.

For example ,let $P\left(x\right)=2$ be a non-zero constant polynomial.

We can write this polynomial like $P\left(x\right)=2x1=2.x^0$

Which shows that The degree of non-zero constant polynomial is $0$.
