To solve the equation \( 4 = x^2 \), you can take the square root of both sides:
\[
x = \pm \sqrt{4}
\]
Calculating the square root of 4 gives:
\[
x = \pm 2
\]
Thus, the solutions are:
\[
x = 2 \quad \text{or} \quad x = -2
\]
So, the final answer is:
\[
x = 2 \quad \text{or} \quad x = -2
\]
\[
x = \pm \sqrt{4}
\]
