Original post by TenOfThem
It is that ... but you need to actually simplify
If you had not multiplied the brackets in the denominator you would have seen how to cancel

Ok, let's assume what you're saying is true - that:
Then this implies two things, firstly it implies that no matter what values of you insert, you always get -1 and secondly it implies that for any two values of x you get the same answer. Neither of which is true. Try - do you get -1?

So, made any progress from where we were last?
You did everything correct apart from dropping the negative, so you can state the correct answer immediately and simplify. Hint: leave the denominator in factorised form.
