I've just started my semester of Calculus and I find limits relatively easy except for these type of questions. Any help would be appreactied, I just need to see it worked out and then I would understand it.

Lim 1/x-1 + 1/x+1 DIVIDED BY x

x-0

I got to:

lim 1/x-1 + 1/x+1

x-0

DIVIDED BY

lim x

x-0

but I dont know what to do after.

Thanks!
