# How do you write a polynomial in standard form, then classify it by degree and number of terms 3x^2 + 5x - 4 + 5x^3?

Refer to the explanation.

#### Explanation:

A polynomial is written in descending order of exponents (powers), remembering that a number without an exponent is actually ${n}^{1}$.

The given polynomial in standard form is:

$5 {x}^{3} + 3 {x}^{2} + 5 x - 4$

The polynomial is 3rd degree because the highest exponent is 3.

The terms in a polynomial are separated by $+$ or $-$ signs.

There are four terms in the given polynomial.
