If you zoom out you can play with the two parabolas of this equation.. hope that helps.

OpenStudy (anonymous):

So factor x^2 - 9....and change division to multiplication by inverting right side. Can you factor x^2 - 9?

OpenStudy (anonymous):

When we divide by (x-3), we are multiplying by 1/(x-3)

OpenStudy (anonymous):

Then I cancelled the (x-3)'s

OpenStudy (anonymous):

I'm left with (x+3)/x

OpenStudy (anonymous):

I've got it. Thank you!
