Step-by-step explanation:

For factoring, if we can ever right a factor as (a)^2 and another as (b)^2 with a MINUS in between them, then the technique of "difference in two squares" is perfect!

From the problem shown, we can actually do this (shown below):

$x^2-25\\=(x)^2-(5)^2$

The rule is a^2-b^2=(a+b)(a-b)

Thus the problem reduces to:

$(x)^2-(5)^2\\=(x+5)(x-5)$

We have use "difference of two squares" here, hence answer choice A is right.
