Question

The degree of a constant polynomial is

• A. $3$
• B. $2$
• C. $1$
• D. $0$

Answer 1

The correct option is D

$0$

Explanation for the correct option:

Option (D):

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

And the polynomial which does not contain any variable is called constant polynomial.

Let $P\left(x\right)=2$ be a constant polynomial,This can be write as

$P\left(x\right)=2x1=2.x^0[As{x}^0=1]$

Which shows that constant polynomial have degree $0$.

Hence option (D) is the correct option.
