Answer 3

I can help you solve equations and other math problems. To solve the equation x^2 + 4 = 0, we can use the following steps:

1. Move the constant term to the right side of the equation: x^2 = -4 2. Take the square root of both sides: x = \pm \sqrt{-4} 3. Simplify the radical using the imaginary unit i: x = \pm 2i 4. Write the final answer as a set of two complex numbers: x = \{2i, -2i\}

These are the only solutions to the equation x^2 + 4 = 0. You can check them by plugging them back into the original equation and verifying that they satisfy it.
