As a data analyst for a logistics company, you are optimizing a cost-prediction algorithm. A segment of the algorithm relies on factoring the expression ${}9x^2 - 12xy + 4y^2 - 49$ to simplify resource models. To write a standard operating procedure (SOP) for junior analysts handling similar models, you must document the correct factorization sequence. Arrange the following steps in the correct order to factor this expression completely.

An inventory analyst uses the polynomial ${}9x^2 - 12xy + 4y^2 - 49$ to model warehouse capacity. When factoring this expression, the analyst first groups the terms as $(9x^2 - 12xy + 4y^2) - 49$. Which factoring pattern must be recognized to simplify the terms inside the parentheses?

An architect is refining a formula for the area of a customized floor panel represented by the polynomial ${}9x^2 - 12xy + 4y^2 - 49$. Match each mathematical expression generated during the factoring process with the correct classification or pattern it represents.

Factoring Industrial Component Models

A structural engineer is analyzing a stress-load formula represented by the polynomial ${}9x^2 - 12xy + 4y^2 - 49$. True or False: One of the linear factors in the completely factored form of this expression is $(3x - 2y - 7)$.
