About This Chapter

The Rational Expressions chapter of this High School Algebra I Tutoring Solution is a flexible and affordable path to learning about rational expressions. These simple and fun video lessons are each about five minutes long and they teach all of the operations involving rational expressions required in a typical high school algebra I course.

How it works:

Begin your assignment or other high school algebra I work.
Identify the rational expressions concepts that you're stuck on.
Find fun videos on the topics you need to understand.
Press play, watch and learn!
Complete the quizzes to test your understanding.
As needed, submit a question to one of our instructors for personalized support.

Who's it for?

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

Struggle with understanding how to multiply and divide or add and subtract rational expressions, solve rational equations, simplify rational expressions, solve inverse variation equations or any other rational expressions 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 rational expressions 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

1. How to Multiply and Divide Rational Expressions

Multiplying and dividing rational polynomial expressions is exactly like multiplying and dividing fractions. Like fractions, we will reduce. With polynomial expressions we use factoring and canceling. I also give you a little mnemonic to help you remember when you need a common denominator and when you don't.

2. Multiplying and Dividing Rational Expressions: Practice Problems

Let's continue looking at multiplying and dividing rational polynomials. In this lesson, we will look at a couple longer problems, while giving you some practice multiplying and dividing.

3. How to Add and Subtract Rational Expressions

Adding and subtracting rational expressions brings everything you learned about fractions into the world of algebra. We will mix common denominators with factoring and FOILing.

4. Practice Adding and Subtracting Rational Expressions

Adding and subtracting rational expressions can feel daunting, especially when trying to find a common denominator. Let me show you the process I like to use. I think it will make adding and subtracting rational expressions more enjoyable!

5. How to Solve a Rational Equation

A rational equation is one that contains fractions. Yes, we will be finding a common denominator that has 'x's. But no worries! Together we will use a process that will help us solve rational equations every time!

6. Rational Equations: Practice Problems

Mario and Bill own a local carwash and have several complex tasks that they must use rational equations to solve for an answer. Enjoy learning how they solve these equations to help them with some of their day-to-day tasks.

7. Division and Reciprocals of Radical Expressions

Watch this video lesson to learn what you need to do when dividing radical expressions. Learn what you need to look out for before you divide and why you can't leave your radical in your denominator.

8. Simplifying Complex Rational Expressions

When it comes to fractions, things may seem to get really complicated and scary when you have a fraction on top of a fraction. But never fear, after watching this video lesson, you will be able to simplify these expressions like a pro.

9. Solving Equations of Direct Variation

In the real world, we come across a lot of problems that vary directly with each other. You will learn how to solve these types of direct variation problems in this video lesson.

10. Solving Equations of Inverse Variation

After watching this video lesson, you will be able to identify problems where you can use the formula for inverse variation to solve them. Learn what is involved and how easy they are to solve.
