1. I Missed the question on the last page! Please tell me others did this too
2. hes joking
3. Seriously guys, do you not make a mental note when you see 'End of Questions' or even check that there isnt a question on the back page? Which there wasnt​, by the way. The archbishop of banterbury is stringing you along

I did it but it was sooooo hard! Loads of people I spoke to didn't do it either!

7 = 5x^2 - 4x - 1 ==> 5x^2 - 4x - 8 x = 0 ==> (4 + 4*root(176))/10 = (4 + 4*root(11))/10

Which then simplifies to (2 + 2*root(11))/5 but I forgot that bit in the exam. Plus that's just the positive root. Read the above discussion about whether the negative one was needed. I personally found both but then said to discount the negative one but don't know if that is correct.
Oh noo! I'm so stupid, for some ridiculous reason I did 2+sqrt-144 / 5

Why I ever thought to do 16-160 is beyond me....

What do you reckon is the most amount of marks I could get for that question?

Urmmm there was... Did you not do the proof question?!
7. (Original post by DOPECYCLIST)
you need the use the discriminant (b^2 - 4ac<0) to determine the fact that it doesn't cross the x axis
No you don't as you found the minimum point of the curve prior to this and the y-value was 1 thus is doesn't cross the x - axis?
8. For the one where you had to factorise f(x) did anyone get (x+1) (x+1) (x+6)
I then made it to (x+1)^2 (x+6)
Was I right in doing so? D:

I thought all dinosaurs were extinct, but it turned out the Bantasaurus species is still doing good
10. how many marks was the solving the quadratic question in 12
11. It was (x-1) (x+1) (x+6)

It is!

It was (x-1) (x+1) (x+6)
pretty sure there was a repeated root..

Can i watch?

It was (x+1)(x+1)(x+6) I remember
