Algebraic Fractions and Brackets

[hypnos]

Hi everyone.
Ok, I'm asking a pretty easy question here for you Maths geniuses but please...don't make fun of me

I know how to simplify equations and multiply out brackets and all that jazz. I know how to simplify algebraic fractions and how to do arithmetic with them...jazz jazz jazz.

I'm having difficulty however when it comes to algebraic fractions and brackets.

Look at this one here for example:

      2a+c        a+2c
3c - {------  -  ------}
        8           4

If someone could just explain how I simplify this I'd be very grateful indeed. As I say, no making fun We can't all be great.

Thanks.

there aren't many people who would make fun of you here. I will try to explain it simplistically, so you or perhaps even less experienced users can understand.

      2a+c        a+2c
3c - {------  -  ------}
        8           4

3c   2a+c        a+2c
--- - {------ -   ------}
1     8            4

24c   2a+c       2a+4c
---- - {------- - -------}
8       8           8

24c    -3c
----- - -------
8        8

27c
----
8

Wow that's a really great explanation. I'll print that so I never forget. Thank you very much.
