Solving quadratic equations powerpoint

Useful , but it would help if you explained some of the numbers that appear. It took me a while to work out where some of them came from.

Sorry about that Sunset. I apologise for any unclear sections but it was 3 years ago I completed GCSE maths and have no concern in fixing this. Sorry. It helped me get an A* so hopefully it will help others. If you need help, please seek other sources.

Good luck!
