Answer:

-2 is the only answer

Step-by-step explanation:

You know the answer can't be a positive number because a positive multiplied by a positive is a positive number. It is not 0 because 0 X anything is 0. -16 x 16 is way to high. But, -2 x 2 = -4

There are no real solutions

Option F is correct.

What is an imaginary number?

An imaginary number is a number that, when squared, has a negative result. Essentially, an imaginary number is the square root of a negative number and does not have a tangible value.

Given equation

[tex]x^{2} =-4[/tex]

Apply square root on both sides of the equation

[tex]\sqrt{x^{2} } =\sqrt{-4}[/tex]

[tex]x=2i[/tex]

2i is imaginary number.

There are no real solutions

Hence, Option F is correct.
