Answer:

B. (x - 2)(x + 2)

Explanation:

The answer is b. If you have (x + a)(x - a), the variables will cancel each other out. For example, if we take the answer (x - 2)(x + 2) and factor it out, we get:

x² - 2x + 2x - 4

Then it becomes just:

x² - 4 because the x to the power of one has been canceled. This proves his theory wrong.
