A software engineer is optimizing a script that uses the expression $(n - 2)^2 + 7(n - 2) + 12$ to calculate the estimated runtime of a data sort. To factor this expression using the substitution method, which substitution for the variable $u$ is required to transform the expression into a standard quadratic trinomial?

A retail analyst is simplifying a revenue model represented by the expression $(x - 2)^2 + 7(x - 2) + 12$, where $x$ represents the number of units sold. To make the model easier to use in a spreadsheet, the analyst decides to factor it using the substitution method. Arrange the following steps in the correct order to complete the factorization.

An inventory analyst is simplifying a logistics formula given by the expression $(x - 2)^2 + 7(x - 2) + 12$. The analyst uses the substitution method to factor the expression for a report. Match each mathematical expression with the specific role it plays in the substitution and factoring process.

A logistics manager is using the mathematical model $(x - 2)^2 + 7(x - 2) + 12$ to estimate warehouse storage requirements. When using the substitution method with $u = x - 2$ to factor this model, the first major transformation results in the standard quadratic trinomial $u^2 + 7u + 12$.

A production manager is simplifying a resource-planning model represented by the expression $(x - 2)^2 + 7(x - 2) + 12$. To factor the expression, the manager first uses the substitution $u = x - 2$ to create the trinomial $u^2 + 7u + 12$. To factor this trinomial, the manager identifies two integers that multiply to 12 and add to 7. Based on the steps for this specific model, if one of these integers is 3, the other integer is ____.
