Write the polynomial in standard form.
sp2606 [1]

The standard form is:

4x^5+3x^2+3

Degree = 5, leading coefficient=4

The 5th degree polynomial is:

Quintic function

it is a trinomial

<u>What is  standard form of a polynomial?</u>

When expressing a polynomial in its standard form, the greatest degree of terms are written first, followed by the next degree, and so on.

So, standard form is:

4x^5+3x^2+3

To find the degree of the polynomial, add up the exponents of each term and select the highest sum ( if there are more than 1 variable in single term) or highest power of variable

Degree = 5

In a polynomial, the leading term is the term with the highest power of x.

So, leading coefficient=4

The 5th degree polynomial is:

Quintic function

It has 3 terms. so, it is a trinomial
