So this question is part of my assignment and from what I can tell, the answer is supposed to come out as zero, but what I get is 1/2. I'm not here just asking for you to do my homework, i'm hoping someone who understands it can explain to me what I should be doing.

You just need to factorize the top and bottom quadratics, then you can cancel out the brackets, OOOOR you can re-simplify them into two of the same quadratics.
And the answer is not meant to be 0. the X>-1 is just saying that X has to be more than -1 but can't equal it. Now go and revise.
Wait doesn't it mean that when X is approaching -1 it gets those values.
There is no limit. Graph it and you can see that when x=-1 it goes to positive and negative infinity.
well i guess you could say if you wanted to that X is any real number but it cant equal -1 because then you would be dividing by 0 and Im afraid in maths thats not allowed.

and you can trust me on this, I've been doing two years of A level maths. i should know.
oh wait. I'm thinking about a different sort of maths, maybe c3 or c4. Im thinking about transformations of graphs where your given a domain and range. I think Im probably wrong though now. Am I?
