A. 1

B. ±√1

C. no real number solutions

D. –1

Answer 1

Answer:

C. no real number solutions

Step-by-step explanation:

Since the square of a number, x, equals a negative number, -1, the answer cannot be a real number because the square of a real number is always non-negative. Therefore, there is no real number solution to this equation.
