  2. False

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The equation x^2 - 1 = 0 has solutions x = 1 and x = -1. The equation x^2 = -1 has solutions x = i and x = -i. Since the solution sets are different, the statement is false.

AI explanation

The first equation x^2 - 1 = 0 gives x^2 = 1, yielding solutions x = 1 and x = -1. The second equation x^2 = -1 yields solutions x = i and x = -i, which are imaginary. Because the solutions are not the same, the statement is False.
