I will show you what I'm looking at it in your drawing: dw:1349027587423:dw

myininaya Group TitleBest ResponseYou've already chosen the best response.2
well what is 3x^2/x^2 is another way of saying it? or since the x^2's cancel then what is 3/1?

myininaya Group TitleBest ResponseYou've already chosen the best response.2
So we put +3 on top of that bar and do what afterwards?
