# How to Simplify Polynomials? (+FREE Worksheet!)

To simplify polynomials, you need to find 'like' terms and combine them. Here you can learn how to simplify polynomials.

## Step by step guide to simplifying polynomials

• Find “like” terms. (they have same variables with same power).
• Add or Subtract “like” terms using order of operation.

### Simplifying Polynomials – Example 1:

Simplify this expression. $$2x(2x-4)=$$

Solution:

Use Distributive Property: $$2x(2x−4)=4x^2−8x$$

### Simplifying Polynomials – Example 2:

Simplify this expression. $$4x^2+6x+2x^2-4x-3=$$

Solution:

First find “like” terms and combine them: $$4x^2+2x^2= 6x^2$$, $$6x-4x= 2x$$
Now simplify: $$4x^2+6x+2x^2-4x-3=6x^2+2x-3$$

### Simplifying Polynomials – Example 3:

Simplify this expression. $$4x(6x-3)=$$

Solution:

Use Distributive Property: $$4x(6x-3)=24x^2-12x$$

### Simplifying Polynomials – Example 4:

Simplify this expression. $$7x^3+2x^4+2x^3-4x^4-8x=$$

Solution:

First find “like” terms and combine them: $$7x^3+2x^3= 9x^3$$, $$2x^4-4x^4= -2x^4$$
Now simplify and write in standard form: $$7x^3+2x^4+2x^3-4x^4-8x=-2x^4+9x^3-8x$$
