Full solution

Q. Find the product. Simplify your answer.\newline(a+4)(a4)(a + 4)(a - 4)
  1. Identify special case: Identify the special case for the product (a+4)(a4)(a + 4)(a - 4). This product is in the form of (a+b)(ab)(a + b)(a - b), which is a difference of squares. Special case: (a+b)(ab)=a2b2(a + b)(a - b) = a^2 - b^2
  2. Apply difference of squares: Apply the difference of squares formula to the product (a+4)(a4)(a + 4)(a - 4).\newlineUsing the formula a2b2a^2 - b^2, we substitute aa with aa and bb with 44.\newline(a+4)(a4)=a242(a + 4)(a - 4) = a^2 - 4^2
  3. Calculate squares: Calculate the squares of aa and 44.a242=a2(4×4)=a216a^2 - 4^2 = a^2 - (4 \times 4) = a^2 - 16
  4. Write final simplified form: Write the final simplified form of the product.\newlineThe product (a+4)(a4)(a + 4)(a - 4) simplifies to a216a^2 - 16.
