1. TuringTest Group Title

$\lim_{x\to2}{1\over(x+2)(x-2)}$?

2. nickymarden Group Title

yeah :)

3. TuringTest Group Title

can you find the left and right hand limits?

4. TuringTest Group Title

$\lim_{x\to2^+}{1\over(x+2)(x-2)}$and$\lim_{x\to2^-}{1\over(x+2)(x-2)}$

5. nickymarden Group Title

so it has 2 answers? i did that already but it says the answer is $1/3\sqrt[3]{4}$

6. TuringTest Group Title

that's not correct...

7. nickymarden Group Title

yeah, thank you. I was just checking :)

8. TuringTest Group Title

sure you're looking at the right problem :P ?

9. nickymarden Group Title

yeah lol

10. nickymarden Group Title

but thank you anyway.

11. TuringTest Group Title

well I'm telling you the answer to the problem you posted is that the limit does not exist, so there must be a typo in your book

12. nickymarden Group Title

i got to the same answer as you, guess the book is wrong then haha.

13. TuringTest Group Title
