Hi All, this is not homework, just some basic revision for my own personal understanding, it's a long time since I went to school?
I would like to refresh my mind on the following algebra please.
4ax + 2ay = 2a x 2x + 2a x y
= 2a(2x + y)
Sorry for not using the DOT product as it does not seem to be available, so had to use X for multiplication?
My misunderstanding of the above is, what happened to the 2a on the right hand side of the first line above?
I understand that 4ax is made up of 2a x 2x = 4ax, and I understand that 2a(2x is made up of the 4ax, but i can't get my head round where the 2a went on the right hand side?
any help greatly appreciated
David
