Standard Form and Integer Criteria in Manufacturing

An HVAC assistant is working with a workshop supervisor to fabricate a custom rectangular ventilation duct. The cross-sectional area of the duct's surplus space is modeled by the algebraic expression 2w+w248{}2w + w^2 - 48, where ww is the width of the duct in inches. Before the team can factor the expression to find the binomial dimensions, the supervisor asks the assistant to state the initial setup requirements.

In a brief essay response, recall and describe the first two steps of the setup:

  1. Explain how to write the expression 2w+w248{}2w + w^2 - 48 in standard form (descending order of degree) and state what the resulting expression is.
  2. Identify the specific product and sum requirements for the two integers that will be used to factor this trinomial (i.e., what value must they multiply to, and what value must they add to).
