Adding
To add the rational expressions and , follow the procedure for adding fractions with a common denominator. Since the denominator is , the restricted value is .
Step 1 — Add the numerators over the common denominator. Both fractions share the denominator , so combine the numerators:
Step 2 — Write the degrees in descending order. Rearrange the terms in the numerator:
Step 3 — Factor the numerator. The trinomial factors into :
Step 4 — Simplify. Divide out the common factor :
The expression simplifies to , with the restriction .

A logistics analyst is combining two shipping rate formulas, represented as rational expressions, that share a common denominator. To ensure the final formula is in its simplest form, what is the correct sequence of steps they should follow?
In a corporate logistics database, when combining two efficiency formulas that share a common denominator, what is the required step after adding the numerators to ensure the resulting expression is fully simplified?
In a professional data report, when a marketing analyst subtracts one rational expression from another that shares the same denominator, the denominator of the resulting expression is found by subtracting the second denominator from the first.
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.
