    If it has equal roots, the value b^2-4ac must equal to 0.
    Substitute b^2-4ac=0 with appropriate values in the quadratic

    No I'm currently doing C1 and M1 for normal maths, and FP1with D1 for Further maths. Will start S1 after D1.
    I didn't like stats at GCSE though... D1 is crap as well. Easy but tedious and boring and repetitive :unimpressed:
