QUESTION SOLVED, HELP RECEIVED

So the question is: "At which points do the tangent lines through (1,2) touch y=x/x+1?"

So I've gone through basically everything (fried my brain this one did):

1. Found derivative using quotient rule; "1/(x+1)^2

2. Equalled the slope of the tangent line that passes through (1,2) and (x,x/x+1) to the derivative and solved for x

3. Got the roots x=-1 and x=-2(+or-)sqrt3

4. Rejected x=-1 because of restrictions

Now I believe that the next step is to plug in x into the original y to complete the point. So, err, how do I go about doing that?
