Hey guys,

I'm sure this is a simple question but I'm new to the area so be gentle

I've an equation with about 6 unknowns. There are 8 terms on the left hand side of the equation, Something like:

and I need to square both sides.

Squaring both sides using pen and paper is a real pain, and I often make silly transcribing errors. Is there any software package out there that can do this for me?

Thanks,

M
