Hi
Can I know how hard people found todays paper please. I think I got 58/70. I just want to see if it was just me struggling more than the past papers or everyone else as well. Thanks
58/70 would have been an A*^ with last years boundaries.

Personally, I thought it was pretty good.

Yeah I think you're right. I was going off what someone got for their answer, which was 45. Now I've remembered I got 65.
I initially got 65, but went back and realised you had to add the LHS to get x root'5' then make the RHS match, so it was 45, which I got in the end. I believe you must have taken away the root'80' and squared everything - which doesn't work unfortunately.

Yep, that's what I did. Ah well, hopefully method marks will be on my side. Plus, got most of the other questions right anyway.

I personally found it easy but i think most people have mixed reactions

I got
1) 3x^2-20x
2) a=3 b=-20
3)n=12 b) 3/5
4)(-5, 8) b)root 10
5) x=39 degrees
6)m=8 p= -1
7) 9, 10, 11
8) x=121
9) x^3-15x^2+75x-125
10) -80
12) h=3 k=-7
13) x=45
14) 3a=3 a=1 b)(x+2)(x-7)(x-3)
15) 2root 7 -4
16) I got 5/6 but answer was -5/6 because it was obtuse
17) k = 9
18) (x^2+9)(x-3)(x+3)
19) 3 + 3 + 3 + 3root 3 is what you get for totals and factorise it to 3 (3+root 3)
20) w = 3n because y use cosine rule and the answer = 1/3 rearrange it and then factorise it into two solutions but answer cant be negative so its n=w/3 and w=3n so two lengthsare equal and u get isosceles
Can anyone remember what question 15 was? I think thats the only one which my results did not corroborate with. Great job btw LokiiR

Surds, where it was surd + surd = surd + root'x'
√125 + √20 = √x + √80
5√5 + 2√5 = √x + 4√5
5√5 + 2√5 - 4√5= √x
3√5 = √x
√45 = √x
x = 45

QED

Pretty sure the answer to question ten is 80 not -80!
its -80 because y was <0 so it was -1/5 not 1/5

Do you know the marks for each question?
I know it for some of them, hang on:
1) 3x^2-20x (2)
2) a=3 b=-20 (3)
3)n=12 (2) b) 3/5 (1)
4)(-5, 8) b)root 10
5) x=39 degrees
6)m=8 p= -1
7) 9, 10, 11
8) x=121
9) x^3-15x^2+75x-125
10) -80
12) h=3 k=-7 b) (-3, -7) (1) c) -3+ or - root 7 (1)
13) x=45
14) 3a=3 a=1 (2?) b)(x+2)(x-7)(x-3)
15) 2root 7 -4
16) I got 5/6 but answer was -5/6 because it was obtuse (3)
17) k = 9 (5)
18) (x^2+9)(x-3)(x+3)
19)prove that the first part = 3, do it by doing sin45 = 1/root2, and 1/root2=x/3root2. Rearrange for 3. b)3 + 3 + 3 + 3root 3 is what you get for totals and factorise it to 3 (3+root 3) (4)
20) w = 3n because y use cosine rule and the answer = 1/3 rearrange it and then factorise it into two solutions but answer cant be negative so its n=w/3 and w=3n so two lengthsare equal and u get isosceles (4)
thats all I can remember...some may not be right, ALSO added answers

Question 15 was I believe rationalising the denominator of a surd. You get to 6root7-12/3 and cancel it down to 2root7 - 4
