To factorize \(x^2 - 4\), we first recognize that this is a difference of squares, which can be factored using the formula \(a^2 - b^2 = (a + b)(a - b)\).
In this case, \(a = x\) and \(b = 2\), so we have:
\(x^2 - 4 = (x + 2)(x - 2)\)
Therefore, the factorization of \(x^2 - 4\) is \((x + 2)(x - 2)\).
In this case, \(a = x\) and \(b = 2\), so we have:
\(x^2 - 4 = (x + 2)(x - 2)\)
Therefore, the factorization of \(x^2 - 4\) is \((x + 2)(x - 2)\).
