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:
Step 2 — Rearrange the numerator in standard form (descending degree order):
Step 3 — Factor the numerator. The trinomial factors as , since and :
Step 4 — Simplify by dividing out the common factor. Cancel the shared factor from the numerator and denominator:
This example demonstrates all three steps of the rational expression addition procedure in action: combining numerators, factoring the resulting polynomial completely, and canceling the common factor with the denominator. Unlike the simpler case 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.
