    Ok, So I was stuck on yet another question from the Edexcel C3 Modular textbook. Exercise 1D(i) question D...

    Q) Use the remainder to express the following improper fractions into 'mixed' number form...

    \frac{2x^2+4x+5}{x^2-1}

    Can anyone check my answers below and tell me what I can do to improve. I'm not sure whether I'm quite right with my answers

    Try splitting the denominator up from x^2-1 = (x+1)(x-1) which is the difference of 2 sqaures

    Cant you just use the long division to get 2 +(4x+7)/(x^2-1) but yeah your way is acceptable.

    As ironic as it sounds, it's a much shorter way to use long division instead.

    Thanks guys. Yeah in actual exam conditions I would most likely be using long division instead of the remainder theorm.

    It's a bit long winded with polynomials on the denominator :/
