THEA Test: Solving Rational Equations - Chapter Summary
This chapter offers an in-depth look at techniques for solving rational equations to ensure you have the knowledge necessary to answer related questions on the THEA test. After reviewing the video lessons, you will be ready to:
- Solve a rational equation
- Add and subtract rational expressions
- Multiply and divide rational expressions
The lessons in this chapter not only reintroduce you to rational equations and expressions, but also offer practice problems that reinforce this subject area. Instructors of the lessons are subject-matter experts who present topics in a fun and engaging manner.
THEA Test: Solving Rational Equations Objectives
In Texas, students interested in attending a public college or university might be required to pass the THEA test to enter as a freshman. The test is broken into three sections that gauge your comprehension of reading, writing and mathematics. Topics in this chapter are found in the mathematics section, which consists of 50 multiple-choice questions. Passing this section of the exam requires a minimum score of 230.
Simplify the process of preparing for the exam by reviewing the lessons in this chapter. You'll find videos as well as written transcripts with helpful vocabulary words. After reviewing each lesson, you can test your knowledge of the topics covered by taking a self-assessment quiz. A chapter exam is also available to gauge your comprehension of all the lessons.
1. 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!
2. 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.
3. 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!
4. 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.
5. 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.
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.
