Answer:(x-4)(x+4)

Step-by-step explanation:This is a special case. Eventually, it will be helpful to memorize these, but for now, this special case is (a-b)(a+b)=(a^2)-(b^2). In this case, a=x and b=4 because the square root of 16 is 4. Plug in your numbers and then you have: (x-4)(x+4) which is your answer!

I hope this helped! 🙂

If your looking for a true or false answer because I didn’t know what type of problem that you were asking, the answer is false because you haven’t factored the equation, if anything, you simplified it. factoring would be what we did above.
