# Writing Polynomials in Standard Form

When working with polynomials, you should always write them in standard form.

## Step by step guide to writing polynomials in standard form

• A polynomial function $$f(x)$$ of degree $$n$$ is of the form
$$f(x)=a_{n} x^{n}+a_{n-1} x_{n-1}+⋯+ a_{1} x+a_{0}$$
• The first term is the one with the biggest power!

### Example 1:

Write this polynomial in standard form. $$8+5x^2-3x^3=$$

Solution:

The first term is the one with the biggest power: $$8+5x^2−3x^3=−3x^3+5x^2+8$$

### Example 2:

Write this polynomial in standard form. $$5x^2−9x^5+8x^3−11=$$

Solution:

The first term is the one with the biggest power: $$5x^2−9x^5+8x^3−11= −9x^5+8x^3+5x^2−11$$

### Example 3:

Write this polynomial in standard form. $$-12+3x^2-6x^4=$$

Solution:

The first term is the one with the biggest power: $$-12+3x^2-6x^4=-6x^4+3x^2-12$$
