Adding and subtracting rational expressions with like denominators is similar to adding and subtracting fractions with like denominators. It is a three-step process: first add the numerators, then simplify the numerator, then simplify the result by factoring. Think of fractions in simplest form because their common factors have been eliminated. Expressions such as 6/8 can be simplified to ¾ because 2·3/2·4. The process is similar with rational expressions. For example, the expression (12y +24)/48y can be simplified by first factoring the numerator 12y +24 to 12(y +2).
