Answer 3

4a²-16 can be simplified by factoring out the greatest common factor, which is 4. This gives us:

4(a²-4)

Then, we can further factor the expression inside the parentheses using the difference of squares formula, which states that a² - b² = (a + b)(a - b). In this case, a = a and b = 2. So, we have:

4(a+2)(a-2)

So, the final simplified expression is 4(a+2)(a-2).
