Multiple Choice

A quality control technician is inspecting a CAD drawing for a square metal plate where the surface area is defined by the formula 4a2−12ab+9b24a^2 - 12ab + 9b^2. To verify that this formula can be simplified to the form (x−y)2(x - y)^2, the technician must confirm that the middle term ($12ab) matches the $2xy requirement of the perfect square pattern. Which calculation correctly demonstrates this specific verification step?
