Ok, so here is the limit question that has been giving me some difficulty:

The lim of x+2 divided by the square root of 6 + x minus the square root of 2 - x as x approaches -2

(Sorry, if I don't know how to put it in symbols otherwise I would >//<; )

Also, any general tips on finding the proper way to "play with"/solve limits would be much appreciated. Thanks for any help in advance!
