Maintaining Procedural Integrity in Technical Calculations

A network engineer is calculating the total data throughput of two parallel server clusters using rational expressions. After rewriting the expressions with a common denominator, the engineer notices that the numerator and denominator of one fraction share a common polynomial factor. According to the standard procedure for adding rational expressions, what is the result of canceling this shared factor before the numerators are combined?
