What are the solution(s) of x squared minus 4 = 0?
x = negative 4 or x = 4
x = negative 2 or x = 2
x = 2
x = 4

The equation is:

\[
x^2 - 4 = 0
\]

We can solve this by factoring the left-hand side:

\[
x^2 - 4 = (x - 2)(x + 2) = 0
\]

Now, set each factor equal to zero:

1. \( x - 2 = 0 \) gives \( x = 2 \)
2. \( x + 2 = 0 \) gives \( x = -2 \)

So, the solutions are \( x = -2 \) and \( x = 2 \).

The correct answer is:

\[
\boxed{x = -2 \text{ or } x = 2}
\]
