If you want to find the limit as

you must resolve your "divide-by-zero" problem.

Therefore, try to factor the denominator to see if we can deal with an factor,

as if

Now, if we can factor the numerator, with as one of those factors,

we will be able to find the limit...

Hence, comparing terms we have

Hence

You can then evaluate the limit if you like.

The limit is evaluated by simplifying the fraction
