Applying the Product of Conjugates Pattern in Metal Fabrication

As a junior cost estimator at a metal fabrication workshop, you are calculating the cross-sectional area of a custom steel bracket. The blueprint represents the dimensions of the bracket's profile using the conjugate binomial expressions (4p7q)(4p - 7q) inches and (4p+7q)(4p + 7q) inches. Rather than performing a lengthy FOIL multiplication, you decide to use the Product of Conjugates Pattern to quickly find the area.

State the algebraic formula for the Product of Conjugates Pattern. Identify the terms corresponding to aa and bb in this specific scenario, show the step-by-step process of squaring these terms, and state the final simplified expression for the bracket's cross-sectional area.
