### 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.
