3 answers

The equation \( x^2 = -9 \) would have no real solutions because the square of a real number cannot be negative. However, there are complex solutions.

In the complex number system, this equation can be rewritten as:

\[ x^2 = -9 \implies x = \pm \sqrt{-9} = \pm 3i \]

Thus, there are 2 complex solutions.

So the equation would have 2 solution(s).

2 is not the answer

I apologize for any confusion. Let's clarify:

The equation \( x^2 = -9 \) indeed has two complex solutions, which are \( x = 3i \) and \( x = -3i \). However, if we are discussing solutions in the context of real numbers, there are no real solutions since \( x^2 \) cannot equal a negative number.

If we consider only the real number solutions, the answer would be 0 solutions.

If your question is strictly about complex numbers, then it would have 2 complex solutions. Please confirm the context you need, and I'll be glad to assist further!
