I can usually do these types of questions, but having the A in there confused me

Any help with part A please?

Treat it as you would any other part of a partial fraction - i.e. by multiplying it by the denominators of the other parts to find the values.

isn't it a top heavy fraction when you multiply out the brakets and everything so then you divide the top by the bottom

You are supposed to use long division. Divide the bottom from the top and you'll get that value for A.

Isn't it just the A(2X+1)(2X-1) + B(2X-1) + C(2X+1) then do what you normally do..?!
