    8-9x = 7100. Solve for x and sub this value into your expansion.

    Danke.I tried that But in the mark scheme they use the value of x=0.1 and placed that into the expansion.

    To be honest the hardest C4 paper I know of is probably last year's which wasn't exactly mind-blowing
    You could go on TeeEm's IYGB thread; the papers are certainly more suitable than Solomon and they are hard

    |x| < 8/9 so don't do 8 - 9x = 7100
    Instead see if there's a nice clean cube factor you can take out and then multiply by at the end
