Now take that number on top (the x^2) and multiply it to your divisor Put the result under the dividend

We are going to subtract that mess Do (that result when you multiply x^2 and x^2+4)

Do that subtraction first then we will put another number on top of that bar

myininaya Group TitleBest ResponseYou've already chosen the best response.2
Yep. That goes on top of that bar.

oh its 9x ?

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?
 2 years ago

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