Best ResponseYou've already chosen the best response.2Do that subtraction first then we will put another number on top of that bar

Best ResponseYou've already chosen the best response.2I will show you what I'm looking at it in your drawing: dw:1349027587423:dw

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