So I think you mean (x^225)/(x5) right? This expression does not exist at x=5 because when you plug in 5 you get something/0 Now when you have 0/0 that means the limit can exist Is there any algebra you can perform to force a function that is continuous at 5?

that isn't how you factor x^225

x^2a^2=(xa)(x+a) you have x^25^2=(x5)(x+5)

OH (x+5)(x5)

right but what do yo notice about the top and bottom (As far as factors go)

You can cancel

right you basically get rid of the discontinuity so you can plug in x=5
