Hi all,

My maths is a bit rusty and I'm at a loss trying to see if the terms
below could be simplified further (I've looked at Taylor series and
geometric series but they won't do the trick):

[(x1-a)^2]*[(x2-a)^2]*[(x3-a)^2]*......*[(xn-a)^2]

Thanks.

There are other ways to write it but none really much simpler.

Perhaps, square only once at the end, thus:

[(x1-a)*(x2-a)*(x3-a)* ... *(xn-a)]^2

Of course, you can also abbreviate your expression as:

Product (as i goes from 1 to n) of (x_i - a)^2

using the usual symbol Pi for product.

quasi
