thanks for ur answer carrotsticks- really appreciate it as well. Do you mind explaining more about the AM-GM Inequality you were mention ing Q1?i'm just a bit confused. also, would u have any idea of which book some of the other questions are from? becos u said Q3 seemed to be from Terry Lee...

thanks for your answer nightweaver- really appreciate it. do u mind telling me how u know how to test x=2/3? and how you get x^{3}-3x+2 as a factor? - i'm just a bit lost.

See questions below, thanks 1. If a > o, b> 0 and c>0, show that \frac{a+b+c}{3}\geq \sqrt[3]{abc} 2. Show that, if x^{3} + px + r = 0 has a root of multiplicity two, then 27r^{2} + 4p^{3} = 0 3. Show that \frac{a^{2} + b^{2} + c^{2}}{3}\left\geq \left ( \left \frac{a + b + c}{3}...

hey- just wondering how do i use latex when typing up my questions? thanks

hey-that's alright. yes please- that would be a big help. thanks heaps, very much appreciated. here is my email: jsmith181@y7mail.com

oh ok but my school's a bit stingy and doesn't give us past papers even though if I ask for it...is there any way i can get some school past papers? cos ive checked the resources and its not that good.

oo really? how should i study for school assessments?

ah i see.. which ones do u recommend i should practice from?

ah ok- thanks for ur help. btw which books do use for ext 2 and ext 1?

>< that is embarassing.. so r they the same as whole numbers?

ah ok i think it makes sense now- wat are "natural numbers"? never heard of them b4.

o ok- because they use J in the polynomial questions of fitzpatrick. i think i remember my teacher saying it was "integer".. so if it stands for integer than what is the difference between an integer(J) and a real number(R)?

fitzpatrick

oh i forgot to ask u- wats the difference between "R" and "J"?

ah ok i see- thanks very much

Spiral- what does Q and R stand for in the fitzpatrick book? and what does it mean for e.g z^4 + 2z^3 + z^2 - 4=0, z is an element (E) of C? just not too sure on these polynomial symbols, thanks.

ok- so how would i go about drawing it then?
