Hey guys, I'm new here, looked for a thread on this and didn't see any...
So, my problem is that I have to find the limit as h approaches 0 of 8/x^2.
I can get to lim h approaches 0 of [8/(x^2+2xh+h^2)-8/x^2]/h and then I get stuck.
I've been working on this problem for well over an hour now, and I can't seem to figure out what I'm doing wrong. I've tried a ton of different possibilities from there, but I always end up with an h in the denominator somewhere in the limit... Any suggestions on how I can get the h out of the denominator so I can solve this? (Sorry for the terrible formatting, I don't know how to make it look better).
