1. Hi
Im doing a c4 paper (link: http://www.mei.org.uk/files/papers/c408ju_op58.pdf)
This is kind of strange because it is supposedly the easiest question, yet i cant figure out how the mark scheme has simplified the fraction??

it's : " express x/(x^2-4) + 2/x+2 as a single fraction"
I have simplified the denominator of the first fraction by factorising it. I just cant figure the next 2 steps. The mark scheme isnt set out clearly

Help??

Thanks
2. Well what did you get when you factorised the denominator of the first term?

To express it as a single fraction, it must have a common denominator with the second term.

So what could you multiply the numerator and denominator of the second term by to give it the same denominator as the first term?
