 Algebra B Math: Operations and Equations with Rational Expressions

This topic continues the discussion on rational expressions. This series of four lessons teaches the student to add and subtract any rational expressions. The series also covers adding and subtracting more than two rational expressions. It finishes with how to solve rational equations.

Adding and Subtracting Rational Expressions: Monomial Denominators

This lesson introduces the student to adding and subtracting rational expressions when the denominators are not equal. The student learns to find a common denominator in order to add or subtract the rational expressions. The student also sees how to simplify the result.

Adding and Subtracting Rational Expressions: Polynomial Denominators

In this lesson, the student learns how to add and subtract rational expressions when the denominators are polynomial expressions that are not equal. This concept allows the student to add or subtract any rational expressions.

Combining More Than Two Rational Expressions

This lesson shows the student how to add or subtract more than two rational expressions. The student learns how to find the common denominator of more than two rational expressions and how to use the common denominator to add or subtract multiple rational expressions.

Solving Rational Equations

This lesson shows the student how to solve rational equations. The student also learns the importance of checking the solutions to prevent any extraneous solutions from occurring.
