Final answer:
The completely factored form of the polynomial is (x + 2)(x - 2), so the correct answer is a) (x + 2)(x - 2).
Step-by-step explanation:
The completely factored form of the polynomial is (x + 2)(x - 2), so the correct answer is a) (x + 2)(x - 2). Let's break it down step by step:
- Expand the polynomial to get x^2 - 4.
- Recognize that the resulting expression is a difference of squares, which can be factored as (x + 2)(x - 2).
