Since x^2 - 25 = (x+5)(x-5),

I'd say x+5 is the greatest common divisor.

Since we have no fractions, I don't think we can talk about denominators. (Unless we are in fact talking about denominators of fractions whose numerators are unspecified ...)

oops. In that case, then (x^2-25) would be the LCD.
