I think this is the thread you're looking for

Check #9 for matrices.

Well, that thread should tell you; perhaps you simply made an error.

If you want further reading on LaTeX or to clear up how to program matrices then go to this excellent website (which is a must for your 'favorites'):

http://www.maths.tcd.ie/~dwilkins/LaTeXPrimer/

EDIT: 'Matrices and arrays' shouldn't be far down the page

Start off with the definition of a determent, then simply plug and chug.

"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."

Are you sure its not this:

because when im trying to solve it im getting negative of the expression

i don't like playing with alpha, beta and gammas so im using

alpha = x beta = y gamma = z

Here it is:

you take the right hand side(RHS) of the expression and then expand it

RHS= (y-x)(z-x)(y-z)

= (yz-yx-xz+x²)(y-z)

= y²z-xy²-xyz+x²y-yz²+xyz+xz²-x²z

(now rearrange them and combine like terms)

= y²z-yz²+xz²-x²z-xy²+x²y

= -1(-y²z+yz²-xz²+x²z+xy²-x²y)

= -1[(yz²-y²z)-(xz²-x²z)+(xy²-x²y)]

=

this is what im getting...so check your question again
