Multiple Choice

A materials engineer is testing a new composite panel with a square surface. The side length of the panel is (4u3+1)(4u^3 + 1) centimeters. To calculate the total surface area, the engineer squares the side length using the Binomial Squares Pattern: (a+b)2=a2+2ab+b2(a + b)^2 = a^2 + 2ab + b^2. Which of the following expressions represents the correctly expanded trinomial for the area?
