    Im self teaching the subject so having a few problems.

    Firstly, does anyone have a detailed specifiction for this unit as I cant find a decent spec on the edexcel website.

    Also, do I need to learn Leibiniz theory and the harmonic mean for this subject as they are in my textbook but its not clear whether they will come up in the exam.

    Thanks.

    Specification

    That link is actually a specification for all Edexcel maths modules, so you'll have to sift through a fair few pages to get to the C3 bit - it starts at page 33

    First thing to do is factorise the denominator of the right most fraction.
    This would go to (x+3)(x-1)
    Then you multiply everything else through by that, so the top and bottom of the leftmost of the 3 fractions is multiplied by (x+3)(x-1), the middle fraction is multiplied by only (x+3) as it already has (x-1) as its denominator.
    This will give all 3 parts the same denominator so you can then just simplify the top easily.
