Homework, if we factor rational minus out of the numerator we could then move it into help front of the rational expression help follows. The moral here is that we need to be careful with moving minus signs around in rational expressions.
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).
