lim x -> 0
1/x - 1/(x^2 + x)
So I simplified this to 1 / x+1
then I sub 0 into x and end up with 1/1.
I have no confidence in myself when I do limits, I failed miserably on my mid term. How can I check if this is true?

You've done a good job here (although I'd have liked to see your working to know for sure that you got 1/(x + 1) by using correct algebra and not by accident). Your answer is correct.
