    any help on long division for C4? i know of the ‘grid’ method, but it seems awfully confusing... i was wondering (hoping!) someone has a method that is slightly less confusing to grasp? thanks!

    Give me an example of a particular problem you are stuck on and I can tell you how I would do it. I don't think it is super complicated the method I use but I think most people use that method.

    x^4-2x^3-7x^2+7x+a is divided by x^2+2x-1

    when quotient is x^2+bx +2
    remainder is cx+7

    i have been given the answers but just the whole algebraic long division seems confusing to me!

    You can use identities or algebraic long division. Note the dividend fits in x^2 into the divisor then complete long division as normal.
