Answer: x= √5, x = -√5

Explanation:

To simplify x^2 = 5, square root both sides to get:

√(x^2) = √5

Then, to simplify √(x^2), you can cross out the √ and the exponent, and add a +-, as the square root of x^2 is |x|, or +-x.

You then get x = √5, and -x = √5, and for the -x = √5, multiply both sides by -1 to get x = -√5.
