what is this (p – q)(2) =

Answer 1

Hello, Ygb,

I'm not sure I have the entire question, but "(p-q)(2) =" means only that 2 times the difference of p-q is equal to something, not stated as far as I can see. It may be asking us to note that (p-q)(2) is also equal to 2p - 2q. Just multiply the 2 by each of the terms inside the parentheses.

In order to get rid of the ( ); multiply.
