See attached image for question. I can cancel out the n to get the answer the textbook gives but I thought this was wrong, propably im misunderstanding this. Started this section on fractions today and still need a good bit of reading and finding my mistakes.....and they are many....

Yeah, that is wrong, and so is cancelling the m's as you have done (can you see why?). :sadnod:

Instead, factorise the denominator (hint: difference of two squares) and see if you can go on.
