Question

(x^4 -16) / (x-2) Evaluate the limit as x --> 2

Answer 1

Completely factor the num'r, and reduce to lowest form. Then it will be possible to just plug in x=2 to get the limit.

Answer 2

Notice that the num'r is a difference of squares. And when you factor, you will have another diff of squares to factor.

Answer 3

Will it be 0 ?

Answer 4

I don't think so. Can you show your work?

What did you get when you factored the num'r?

Answer 6
