 How to simplify rational expressions?
How to simplify rational expressions? The rules of addition, subtraction, multiplication and division of rational expressions are used to simplify complex expressions.
Rational expressions are multiplied as follows: We divide two rational expressions by multiplying the first rational expression by the reciprocal of the second rational expression as follows: If you have difficulties in simplifying rational expressions, review the tutorials in How to Add, Subtract and Simplify Rational Expressions and How to multiply, divide and simplify rational expressions and then start the present tutorial. The examples with detailed solutions and explanations in this tutorials will help you overcome any difficulties in simplifying rational expressions on the condition that you understand every step involved in solving these questions and also spend more time practicingif needed. I will present the examples below starting with fractions first and then with rational expressions, with more challenging questions as you walk through the tutorial. You need to understand each step!
Example 1: Simplify: .
Example 2: Simplify: . Solution: We simplify by converting to the same denominator using the LCD of (x  2) and (x + 1) which is is (x  2)(x + 1) and applying the rule of the sum of two rational expressions. Example 3: Simplify: . Solution: We simplify by converting to the same denominator Example 4: Simplify: Solution: Apply the rule of subtraction of rational expressions to and then simplify. Apply the rule of division of rational expressions ( which becomes a multiplication by the reciprocal ) and factor and simplify
Example 5: Simplify:
