guys can u explain q18 b(ii) and (c) I did not understand
here is link http://papers.xtremepapers.com/CIE/Cambridge IGCSE/Mathematics (0580)/0580_w11_qp_21.pdf
plz
I have an exam on may6 plz guys

for b(ii), use the difference method...
find the 1st 5 terms then take out the difference. like this:-
4 9 16 25 36
5 7 9 11
2 2 2
2nd row is the diff. btn the nos. in 1st row and 3rd row is diff. btn nos. in 2nd row. and since its a quadratic function (ax^2+bx+c)
2a=2, so a=1
3a+b=5, so b=2
a+b+c=4, so c=1
the function is x^2+2x+1
got it?

Same here! I'm going through each chapter and doing a few questions from the exercises in the book and then I'll do the past papers properly in the last 3-4 days. I just hope the exam would be easy for all of us, especially P4. :/

I'm very concerned about Paper 6 for the Intl. Maths, we've done all the papers in class but its absurdly challenging. Best of luck to all people here which is taking the P2 tomorrow!
