Best ResponseYou've already chosen the best response.0Easiest way to check: Plug in x=1 for x in the first equation, then do the same for the other four. If you get the same answer then that's it.

Best ResponseYou've already chosen the best response.0Or choose another number, something obscure, like 12. But you can also find it by expanding out and combining like terms. (x+2) + (x2)(2x+1) = (x+2) + (2x^2 + x 4x 2) = 2x^2 2x A.
