Adding
Add two rational expressions that share the polynomial denominator :
Step 1 — Add the numerators over the common denominator. Because both expressions already have the same denominator, combine the numerators:
Step 2 — Check whether the numerator and denominator can be factored. The numerator and the denominator share no common polynomial factor, and neither can be factored further.
The fraction is already in simplified form.
This example illustrates that after adding the numerators of two rational expressions with a common denominator, the result may already be fully simplified — not every sum requires the factoring and cancellation steps.

A technical specialist is documenting the standard operating procedure (SOP) for combining algebraic performance metrics (ratios) that share a common denominator. Match each stage of the 3-step procedure to the correct action required to ensure the final formula is accurate and simplified.
Procedural Steps for Combining Efficiency Formulas
In a professional data analysis report, when an analyst adds or subtracts rational expressions that share a common denominator, they first combine the numerators. According to the standard 3-step procedure, the analyst must then ____ both the numerator and the denominator completely to identify any shared factors that can be simplified.
