Math Problem Help

[Umpalumpa]

Ok well I got this math problem today for extra credit and wanted to know if anyone knew a simple way to do it.

Its a factoring type of problem-
Example (x-A)(x-B) = (x2-B-A +BA)
(x-a)(x-b)(x-c)(x-d)(x-e)......All the way to (x-z)

[Mr.cool]

simple its just all of that times 2 which would equal X2 a-b-c-d-e-f-g-h-i-j-k-l-m-n-o-p-q-r-s-t-u-v-w-x-y-z + ABCDEFGHIJKLMNOPQRSTUVWXYZ

that isn't even right.

(x-a)(x-b)

x^2 - xb - ax + ab
x^2 - (a+b)x + ab

as for your problem like hell am I going to do it. It'll start off with X^26 though, but I'm sure you'll see the pattern

[Umpalumpa]

well would it be x2 or x26-a-zX+a-z?

He is right.

Remember, FOIL is your friend!

BTW, CaloTyst, love that sig quote. Who said that?

I don't know, I laughed at it since it was rediculous.

Anyways foil sucks. I just multiply every term by everything. I find it faster... and speed is what math is about.
