A facilities manager is analyzing a floor plan where the area of a storage unit is represented by the expression $r^2 - 8rs - 9s^2$. To determine the lengths of the sides, the manager must factor the expression. Which of the following is the correct factored form?

A coordinator needs to factor $r^2 - 8rs - 9s^2$ to find the dimensions. The coordinator must identify two numbers that sum to ____

A technical writer is creating a training manual that explains how to factor the area expression $r^2 - 8rs - 9s^2$ using the two-variable trinomial strategy. Match each component of the expression with the correct role it plays in setting up the binomial factors.

A facilities coordinator is documenting the process for factoring the area expression $r^2 - 8rs - 9s^2$ for a project report. Arrange the following steps in the correct order to complete the factorization using the two-variable trinomial strategy.

Sign Determination in Multi-Variable Factoring

A facilities coordinator is auditing a floor plan where a specific zone's area is modeled by the expression $r^2 - 8rs - 9s^2$. True or False: The correct factored form of this expression, representing the zone's dimensions, is $(r + s)(r - 9s)$.

Standard Operating Procedure: Factoring Two-Variable Trinomials

An inventory analyst is using the expression $r^2 - 8rs - 9s^2$ to model the distribution of two types of stock. To factor this expression using the two-variable trinomial strategy, which pair of numbers must be identified because they have a product of $-9$ and a sum of $-8$?

An operations analyst is reviewing a resource distribution model represented by the expression $r^2 - 8rs - 9s^2$. When applying the two-variable trinomial factoring strategy to determine the model's components, which variable must be included in the second term of each binomial factor?
