no real solution

+4
-4
infinite solutions

Answer 1

There are no real solutions to the equation x^2 = -16 since the square of any real number is always non-negative. However, there are infinitely many solutions in the complex number system. One possible solution is x = 4i, where i is the imaginary unit (√(-1)).
