Yea all the best May God help us all
Mj12Helllo Can someone Solve June 2012 Paper 13 Question 3 and October 2014 paper 13 Plzzzzz. Also who is sitting in variant maths 9709 p12?
W14 also question 3??Helllo Can someone Solve June 2012 Paper 13 Question 3 and October 2014 paper 13 Plzzzzz. Also who is sitting in variant maths 9709 p12?

Yasss , sorry silly me I forgot to state which question. Its question three w14 p13 But omg thanks a buunch for Binomial expansion ! xxW14 also question 3??

(i)
1) 9x^2 - 12x + 5
2) 9(x^2 - 4/3x + 5/9)
3) 9((x - 2/3)^2 + 1/9)
4) 9(x - 2/3)^2 + 1
-> 1(3x - 2)^2 + 1
(ii)
d(3x^3 - 6x^2 + 5x - 12) / dx
9x^2 -12x + 5 = 9(x - 2/3)^2 +1
f'(x) always > O so increasing function.

btw i added nummbers to ur steps so you could know which step i am referring too. Also 9 (a) The first term of an arithmetic progression is −2222 and the common difference is 17. Find the value of the first positive term. [3] (b) The first term of a geometric progression is ï3 and the second term is 2 cos 1, where 0 < 1 < 0. Find the set of values of 1 for which the progression is convergent. Can you solve question 3b for mehh and explain )? This question is in http://papers.xtremepapers.com/CIE/...S Level/Mathematics (9709)/9709_s15_qp_13.pdf if you dont understand it hereHey how did u transform the thing from step 3 to step 4 (like where did the 1/9 go ? and then from step 4 to the answer (where did the 9 go and what happened to the values inside the brackets.)

f(-b/2a)http://justpastpapers.com/wp-content/uploads/2015/05/IMG_5219.jpg
12/m/j/15 - q11 ... Why should it be 1/2 <g(x)<13 and not 5 instead of 1/2 as calculated from domain?
-b/2a??f(-b/2a)
f(3/2) = 1/2
Vertex y value, as it will be the lowest the range will be from there to the highest value of domain substituted in f(x).-b/2a??
