This type of statement is called a difference of squares. If you see an equation in the form:
a2 - b2
then it is also equal to:
(a + b)(a - b)
In this case 9x2, and 25 are both perfect squares. 9x2 is equal to (3x)2 and 25 is equal to 52, so the that statement can be factored out as:
(3x - 5)(3x + 5)
