Answer:
B. (x - 2)(x + 2)
Step-by-step 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.

A)5x = 122+3
5x = 125
x = 125/5
x = 25
B) 3x = 81-3
3x = 78
x = 78/3
x = 26
