Default C3 Algebraic Fractions
 
Can anyone help me out with these questions? They are from the edexcel c3 textbook exercise 1e (questions 1d and 4)

(x + 1/x - 2)/x-1


f(x) = x + 3/(x-1) -12/(x² + 2x - 3)

show that f(x) = (x² + 3x + 3)/x+3

Thanks

You can use TeX to efficiently write math such as [Mimetex cannot convert this formula] and [Mimetex cannot convert this formula] on your computer.

To use it on the forum you simply write the TeX content between [ tex] and [ /tex] tags (delete the space) - to see what someone actually typed to generate the input simply try to reply to their message - it's fairly logical though slightly daunting at first.

You will want to use the proper software for free on your computer which has many many more features for producing proper documents (output as pdf files) and the font is considerably better than that generated on the forum - follow the instructions to install software here:

A quick reference to just a few of the symbols available:

May I just say that one of the links to download the TeX Centre didnt work for me. I had to look for it elsewhere
