here im going to ask some questions............

lets see who answers first!!!!!!! then i will give u a new one!!!!!!!!!!

any body can suggest questions

rule #1-----dont post a question till someone answer the current question...!

rule# 2-----remember the first rule!!!:D:D


1. (x-y)(x-y)= x^2 +2xy + y^2 you know this expansion...

ad even (x-y)(x-y)(x-y) =x^3 - 3x^2y+ 3xy^2 -y^3

note: "^" symbol to denote power...



so can u expand (x-a)(x-b)(x-c)...........(x-y)(x-z) ????????

what is the answer????

    Where I'm now
    This answer is very complicated.Since Z is 26th letter It will be Z^26-(a-b+c..-Z)X^25+(ab-bc+cd...)X^24.........+ABCDEFGHIJKLMNOPQRSTUVWXYZ.

    So now its my time to answer___________

    it is zero

    (x-a)(x-b)......(x-x)(x-y)(x-z)

    (x-x) = 0 so answer is obvious can anybody start the second question....

    it can be of any subject......you can google and put the answer before 10 post exceed here after after 10 posts put the answer!!!!
