Question

solve the following quadratic equation.
$x^2 = 64$
enter multiple answers separated by a comma or enter none if there are no real solutions.

Explanation:

Step1: Take square root of both sides

To solve \( x^2 = 64 \), we take the square root of both sides. Remember that when we take the square root of a number, we consider both the positive and negative roots. So we have \( x=\pm\sqrt{64} \).

Step2: Calculate the square root

We know that \( \sqrt{64} = 8 \), so substituting that in, we get \( x = 8 \) or \( x = -8 \).

Answer:

8, -8
