The expression \(x^2 - 49\) can be factored using the difference of squares formula, which states that \(a^2 - b^2 = (a - b)(a + b)\). In this case, you can rewrite the expression as follows:
\[ x^2 - 49 = x^2 - 7^2 = (x - 7)(x + 7) \]
So, \(x^2 - 49\) factors to \((x - 7)(x + 7)\). If you were looking for something specific, such as solving for \(x\) or something else, please let me know!
