Question

Find the degree of the following polynomial.
$x^3+17x-21-x^2$

Answer 1

In the given polynomial $x^3+17x-21-x^2$, the exponents of the variable $x$ are $3,2$ and $1$.

We know that the highest exponent of the variable $x$ is the degree of the polynomial.

Hence, the degree of the polynomial $x^3+17x-21-x^2$ is $3$.
