Question

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

Answer 1

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:

`5x^3+3x^2+5x-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.
