    Guys what was the equation that you had to complete the square on??
    I think.... 3x^2+12x+13?

    Wait I thought for the one being above the x axis you work out te min y value and show its greater than 0.

    At least that's what I've seen on past mark schemes?
    Yes that's what I did, I found the turning point which shows that that the minimum point of Y is a positive and is therefore above the x-axis.

    By that you mean k>14/3 ? That's what I got

    i cant remember the equation but the answer was (x-2)^2+1 simply multiply the thing out to get the original equation

    I hated the binomial expansion question and finding the values of K!!!! I think I flopped 😞

    I completely agree, i absolutely love when they give you 14marks for the graph questions! Just praying that the induction question isnt too tricky!

    I like the induction questions since if you don't get the result you're expecting you know you've gone wrong. Plus you get 2 marks for writing 2 sentences

    yep (-2,1) was the minimum point for the last question. you needed it for the last question to work out K btw that's was 5
    22 root 2 was also right
    (0,3) was right and so is (0,7). you worked it out by putting x and y equal to 0 separately to find X and Y respectively.
    question 12(i) required you to find K by putting the quadratic equal to Zero. and solving to find K
    It was (0,-3) and (0,7) according to my maths teacher

    Relative to other papers, how hard do you think this was?
    I'm guessing 59/72 for A

    Yes me too, however you dont get those two marks unless youve got the previous bit right or atleast most of it right!

    Hang on wasn't there a 3 that you had to factorise out?

    For the transformation question number 10, did everyone get that to get f(x) to g(x) it was f(x) - 36? Also once proving g(-1) was a root did anyone get that the 2 other roots were -1 again (repeated) and then 6?

    What did people get for the triangle question which got you to form the equation 5x^2-4x-1=h^2?

    I used Pythagoras also do I lose marks for nt simplifying my fractions? I don't think it asked us to do so anywhere?

    I also mucked up my polynomials but couldn't figure out where so lost a few marks there

    For 12(i) I put 56/12 rather than 14/3, will I lose a mark because I forgot to simplify it?
