    Am I the only one that found this question really easy?
    Don't you just use b^2-4ac and see where it is greater than 0?

    Omg I did as well! I figured it out as soon as I started working through it

    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

    Question Paper, courtesy of Nels98: http://www.thestudentroom.co.uk/show...819&p=55753987
    Props to Mathbomb for writing this with me

    1. r = \sqrt{\dfrac{A}{\pi(x+y)}} (2 marks)

    2. y = 4x + 10
    Intersection with axes:
    (0, 10), (-2.5, 0)
    (5 marks)

    3a. 1 (1 mark)

    b. 0.6 (3 marks)

    4. x < -1.2 (3 marks)

    5. (7/8,19/8) (4 marks)

    6a. 6\sqrt{5} - 31 (3 marks)

    b. 22\sqrt{2} (2 marks)

    7. 81x^4 - 216x^3 + 216x^2 - 96x + 16 (4 marks)

    8a. Use Pythagoras (2 marks)

    b. x = \dfrac{2+2\sqrt{11}}{5} (3 marks)

    9a. False because rhombuses/kites can have diagonals intersecting at 90 degrees. Should be => (2 marks)

    b. False; many examples where x^2 is an integer and x is not, e.g. x^2 = 2 so x = \sqrt{2}, which isn't an integer. Should be <= (2 marks)

    10a. Should hit x-axis at -3, 2 and 5, y-axis at 30 (3 marks)

    b. Expand brackets (2 marks)

    c. Translation by the vector
    \begin{pmatrix}

0 \\

-36

\end{pmatrix} (2 marks)

    d. (x+1)^2(x-6) (5 marks)

    11a. centre is (10,2), r = 5\sqrt{5} (2 marks)

    b. A(-1, 0), B(21, 0), D(0, -3), E(0, 7) (4 marks)

    c. y = 3x - 28 (6 marks)

    12a. k &gt; 14/3 (5 marks)

    b. 3(x+2)^2 + 1 (5 marks)

    c. k = 5 (2 marks)

    Enjoy, hope you all got what you wanted!

    Did any one get fractional answers for the point of intersections on question 4 I think it was.

    Did someone put 22 ROOT 2 for the surd question.

    Did people get -2,1 for the minimum point on the last question.
    Yup to all of those but I may have got the fractions wrong. My friend got different answers and I didn't have a chance to ask around.

    you need the use the discriminant (b^2 - 4ac<0) to determine the fact that it doesn't cross the x axis

    Yeah exactly that, answer came out to be 14/3 when simplified.

    Can you make a mark scheme with questions and answers on? Think everyone would appreciate it 😄

    anybody want me to make an unofficial markscheme?
    Yes please, praying to god for 98-100UMS on this!

    Anyone doing FP1 tomorrow?

    Does anyone know the mark normally needed for 100 UMS?

    I'm guessing 72, right?

    Yeah, I quite like FP1 since much like Core 1 they almost always have the same questions just slightly different on every paper.

    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?

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

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