Question$25 x^{2}-1$

Studdy Solution
Apply the difference of squares formula, which states that $a^2 - b^2 = (a - b)(a + b)$.
For our expression:
$$(5x)^2 - 1^2 = (5x - 1)(5x + 1)$$
Thus, the expression $25x^2 - 1$ factors to:
$$(5x - 1)(5x + 1)$$
The factored form of the expression is:
$$\boxed{(5x - 1)(5x + 1)}$$
