To add or subtract rational expressions with a common denominator add or subtract the numerators and place the result over the common denominator We always simplify rational expressions Be sure to factor if possible after you subtract the numerators so you can identify any common factors Adding and subtracting rational expressions (different denominators) Numerical fractions. To understand how to add or subtract rational expressions with different denominators, let's first examine how this is done with numerical fractions. For example, let's find 2 3 + 1 2 . = 2 3 + 1 2 = 2 3 ( 2 2) + 1 2 ( 3 3) = 4 6 + 3 6 = 7 6.

Adding And Subtracting Rational Expressions

Adding And Subtracting Rational ExpressionsAdding and subtracting rational expressions is identical to adding and subtracting integers. Recall that, when adding fractions with a common denominator, you add the numerators and keep the denominator. This is the same process used with rational expressions. Remember to reduce the final answer if possible. Example 8.4.1. Adding and subtracting rational expressions is similar to adding and subtracting fractions Recall that if the denominators are the same we can add or subtract the numerators and write the result over the common denominator
