okay, well there is a simpler way... so you know that it will be like this... cuz that would mean its the most simplified it can get... do u understand? |dw:1357969192178:dw| sorry its a little weird.. does that make sense??

and @Azteck that is true, but i think i have a more simple way.. since it's using the FOIL method.. do u know the FOIL method @vortish?
