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?

Basically is there any factoring you can do?

that isn't how you factor x^225

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

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

and you have (x+5)(x5)/(x5)

You can cancel

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