x2-26

It seems like you have an expression \( x^2 - 26 \). Are you looking to factor it, solve for \( x \), or perform some other operation? Here are a couple of things you can do with the expression:

1. Factoring: The expression can be recognized as a difference of squares if you rewrite it as \( x^2 - (5\sqrt{2})^2 \): \[ x^2 - 26 = x^2 - (5\sqrt{2})^2 = (x - 5\sqrt{2})(x + 5\sqrt{2}). \]

2. Solving for \( x \): If you set the expression equal to zero: \[ x^2 - 26 = 0, \] you can solve for \( x \): \[ x^2 = 26 \implies x = \pm \sqrt{26}. \]

Let me know what specific operation or additional information you are looking for!
