Completing The Square

I think it's time for me to share knowledge :). 

Since I am a mathematics teacher, I'd like to share a power point about algebra. The chapter is Quadratics. The book that I use is published by Cambridge.

So, for you, who face a trouble about Quadratics (pure math 1) you can download this power point.

It is very useful. And I got this for free, so I share it for free too.

Have a good time :)
