Homework Statement



I'm in the early stages of Calculus I.. just doing the basics you learn in the Calc prep course.
This one problem is really getting me confused.


Homework Equations



Lim -> 0 in the function 1/x(1/(x+2)^2 -1/4)

The Attempt at a Solution



I've tried foiling and cancelling, it hasn't worked.
I've tried a^2 - b^2 formula to cancel, that hasn't worked either
Tried using a conjugate without a root and that doesn't work
Would this be a case where 'The Squeeze' method would be necessary? Or is there a better way.. Thanks in advance
 
Physics news on Phys.org
After about 10 attempts later and numerous sign errors and not simplifying stuff enough i finally got an answer of -1/4.. Thanks anyway guys!
 
Can try L'Hopital rule?
 
Lim -> 0 in the function 1/x(1/(x+2)^2 -1/4)

Do you mean this?

[tex]\lim_{x\to 0}\frac{1}{x} (\frac{1}{(x+2)^{2}} - \frac{1}{4})[/tex]
