Haha thanks!I found this on yahoo : https://in.answers.yahoo.com/question/index?qid=20110603222454AAcn1Xy
Both.Some article got me confused, a quadratic equation can have both maximum and minimum points or just one of them?
No problem.Haha thanks!
Thought blocker can you explain please ? .. the steps in that site are non- logical ... why can't we cancel and why can't we substitute u in place of sqr root (x+1) in the dx !!

I cannot get the pic of the question. But figuring from the markscheme there is some mistake. Simplifying with surd rules it should be 10 cbrt(7.1) hence x can be 0.1. Upload the question again dude.So Can some one help me with PART B ofthis question? This is from edxcel june 2013R

I have no Idea how to do it. I tried marking scheme and its more confusing, I usually use examsolutions but solution of this paper is not there.
He is the marking scheme of this question. How did they get 71 there? Not to mention how did they get x=0.1?!

8-0.9 = 7.1 ?cube root 7100 can be written as cube root 71 * 100
ths can further be written as surd form like 10 cube root 71
using ur expansion 71 =( 8 - 9x )
replace this in the surd form expression...it will become 10 cube root ( 8 - 9x )
PS i need the expansion to get the result x=0.1
upload it plz. im too lazy to work tht out.
btw u need to replace ur expansion cube root ( 8 - 9x ) in the surd form n expand. n solve for x using quadratic formula judging from the answer 0.1
wht?8-0.9 = 7.1 ?
