D
Correct answer
Explanation
(x-1)(x+1) = 0 implies x = 1 or x = -1. Since x can be either 1 or -1, and Quantity B is 0, we cannot determine if A > B, A < B, or A = B.
AI explanation
Applying the difference of squares identity to (x - 1)(x + 1) = 0 results in x^2 - 1 = 0, which gives x = 1 or x = -1. Since Quantity A is x, it can be either 1 or -1, while Quantity B is 0. Because one root is greater than 0 and the other is less than 0, a definitive relationship cannot be determined.
