y = -x^2 + x +2 let x=0 to find y intercepts y=2 therefore y intercept is (0,2) let y=0 to find x intercepts 0 = -x^2 + x +2 x^2-x-2=0 (x-2)(x+1)=0 x=2,-1 therefore x intercept is (2,0) and (-1,0) since it is y = -x^2 + x +2 it is a concave down parabola since the coefficient of x^2...

coincidence?

damn just found 4 places to download it from but the site costs $25 higher algebra by hall and knight Full Version Download higher algebra by hall and knight Full Version Download higher algebra by hall and knight Full Version Download higher algebra by hall and knight Full Version Download

maybe theres an e-book of it

thanks bros

u can fuck off to you smartass edit: @ undalay

k fuck off if you arent going to be helpful

yea but it wont properly prepare u for question 8 which u wont be allowed to do again and again

Math and English

LHS=ln2 RHS=-ln(1/2) =-ln(2^-1) =--1ln2 =ln2 =LHS LHS=RHS :. ln2=-ln(1/2)

ppl already can do it in the time allocated

why would u say that

source?????

who else here listens to max b?

it would be better to do 100s of papers

hes a pedo and his textbook is shit. cambridge is way better

1a) show that x^n-bx^2+c has a multiple root if (n^n)(c^n-2)=(4b^n)((n-2)^(n-2)) b)Show co4@=8(cos@-cosPI/8)(cos@-cos3PI/8)(cos@-cos5PI/8)(cos@-cos7PI/8)

"Then an Extension 2 Mathematics HSC Judge (Rodney Miller) got up and said he has never been able to complete an Extension 2 paper in the time allotted, and on average it takes him 6-10 hours to complete such an exam. " lol moron
