# How do you write a polynomial in standard form, then classify it by degree and number of terms  1 - 2s + 5s^4?

Jan 15, 2018

#### Explanation:

When you want to write a polynomial in standard form, we need to put the variable with the highest degree first, and the number last.

Our highest degree here is the $5 {s}^{4}$, and our number is $1$.

Our standard form polynomial is $5 {s}^{4} - 2 s + 1$.

To classify it by a degree, we also look at the variable with the highest degree, $5 {s}^{4}$. So our degree of the polynomial is 4th degree .

There are three terms in this polynomial: $1$, $- 2 s$, and $5 {s}^{4}$, meaning that this polynomial is a trinomial.

Hope this helps!
