Completing the Square Information ppt

This is a nice powerpoint which has a clear worked question showing how to complete the square and use this to interpret the vertex of the quadratic. You could use this as part of a lesson on completing the square but it would need some more examples and a consolidation activity adding in. Sadly the animations don't work properly, as new animations appear the old ones are not programmed to disappear, this would take a few minutes to sort out. Thank you for sharing.
