## Who's it for?

This chapter of our high school algebra I tutoring solution will benefit any student who is trying to learn cubic equations and earn better grades. This resource can help students including those who:

- Struggle with understanding how to solve perfectly cubed equations, use the greatest common factor, use grouping to factor cubic equations, square both sides of an equation twice or any other cubic equations topic
- Have limited time for studying
- Want a cost effective way to supplement their math learning
- Prefer learning math visually
- Find themselves failing or close to failing their cubic equations unit
- Cope with ADD or ADHD
- Want to get ahead in high school algebra I
- Don't have access to their math teacher outside of class

## Why it works:

**Engaging Tutors:**We make learning cubic equations simple and fun.**Cost Efficient:**For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.**Consistent High Quality:**Unlike a live high school algebra I tutor, these video lessons are thoroughly reviewed.**Convenient:**Imagine a tutor as portable as your laptop, tablet or smartphone. Learn cubic equations on the go!**Learn at Your Pace:**You can pause and rewatch lessons as often as you'd like, until you master the material.

## Learning Objectives

- Define cubic equations.
- Solve equations that are perfectly cubed or not perfectly cubed.
- Use the greatest common factor to solve cubic equations.
- Factor cubic equations using the process of grouping.
- Solve cubic equations that have integers as the solution.
- Convert radical equations into linear or quadratic equations.
- Understand how and when to square both sides of an equation twice.

### 1. What is a Cubic Equation? - Definition & Examples

In algebra, you come across various kinds of functions. You start learning about linear functions, and then quadratic functions. Now, though, you come across cubic functions. What are they? Watch this video lesson to find out.

### 2. How to Solve Perfectly Cubed Equations

Watch this video lesson so you can identify perfectly cubed equations. Learn about the formula that helps you factor them and then to solve them. See how easy it is to use these formulas.

### 3. How to Solve Equations that are Not Perfectly Cubed

Watch this video lesson to learn what to do when you have a cubic equation that is not perfectly cubed. Learn an easy method to find all three roots or solutions.

### 4. Using the Greatest Common Factor to Solve Cubic Equations

Watch this video lesson to learn how to identify the cubic equations for which you can factor out the greatest common factor to help you solve them. Learn the steps you need to take to solve them.

### 5. Grouping to Factor Cubic Equations

Factoring a quadratic equation may seem super easy to you now as you step into the world of cubic equations. Watch this video lesson to learn one easy method that you can use to factor some cubic equations.

### 6. Solving Cubic Equations with Integers

Solving quadratic equations is one thing since you have the use of the quadratic formula, but what about solving cubic equations? Watch this video lesson to learn an easy method you can use to help you solve them.

### 7. Changing Radical Equations into Linear or Quadratic Equations

There are all kinds of equations you have to learn how to solve. In this video lesson, you will learn how to remove the radical symbol so you can easily solve equations with radicals in them.

### 8. Squaring Both Sides of an Equation Twice

Okay, so you got the whole solving for x part down. But what will happen if your x is inside a square root? What do you do then? Watch this video lesson to learn what you can do.
