Blueprint Specification Simplification

A junior technical drafter is updating a CAD blueprint for a custom-sized ventilation panel. The area of the panel is currently represented by the expression (3+5x)(35x)(3 + 5x)(3 - 5x) square inches. The drafting supervisor asks the drafter to record the simplified version of this area in the 'Technical Specifications' column using the Product of Conjugates Pattern (a+b)(ab)=a2b2(a + b)(a - b) = a^2 - b^2. Based on this pattern, what is the simplified expression the drafter should enter into the specifications?
