Adding
Add two rational expressions that share the denominator , then factor and simplify: Step 1 — Add the numerators over the common denominator. Since both fractions share as their denominator, combine the numerators: . Rearranging the numerator into standard form (descending degree order) gives: Step 2 — Factor the numerator and denominator completely. The trinomial factors as , since and . The denominator cannot be factored further: Step 3 — Simplify by dividing out the common factor. Cancel the shared factor from the numerator and denominator: . This example demonstrates the three-step rational expression addition procedure in action: combining numerators, factoring the resulting polynomial completely, and canceling the common factor. Unlike simpler cases where the combined numerator cannot be factored, here the trinomial numerator shares a binomial factor with the denominator, reducing the expression to a simple binomial.

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.
