Adding/Subtracting Rational Expressions

This worksheet contains a good selection of problems of adding and subtracting rational expressions. There are eight problems. None of the problems have common denominators.  A few are mixed expressions and some require factoring....

There's a fine line between a numerator and a denominator! Learners find common denominators in order to add and subtract rational expressions. Examples include addition, subtraction, and complex fractions.

This worksheet contains 10 problems on subtracting rational expressions. It starts out with like denominators and progresses to more complicated problems. Answers are included. 

Lets keep the system working and show learners the three ways to solve linear systems of equations. Each method includes step-by-step instructions to work their way through the problem. The same problem is used for each method to show...

Combine a video with the lesson on combining rational expressions. Young mathematicians first review how to add and subtract rational numbers. They then learn how to apply the same reasoning to add and subtract rational expressions by...

"Sal, why do we care? Why must we rationalize denominators?" Acknowledging these (possibly pleading) concerns, Sal explains the reasons behind rationalizing a denominator before demonstrating how to do it several times. Though he admits...

Use Glencoe's Math Course 3 randomly generated self-checking quiz to test your knowledge of adding and subtracting fractions with like denominators. Each question has a "Hint" link to help. Choose the correct answer for each problem. At...

Video showing how to add and subtract rational expressions by finding a common denominator and then simplifying the result. Also includes finding the domain of the result. [8:15]

Video shows example of adding and subtracting rational expressions. Includes discussion of using the least common multiple of the denominators for a common denominator. [2:56]

Demonstrates how to subtract rational expressions. Each of the rational expressions can be simplified before finding common denominators and performing subtraction. [2:52]
