solving quadratics

Описание к видео solving quadratics

here is a math video tutorial about quadratic equations. it was done as an impress presentation using some free video-screen-capture software. also, used the headset - for those who like it ;-) for those who find it too noisy, sorry :-/ it was what was easiest.

thanks everyone for all of your support, sorry I don't have time to respond to every comment... but I do appreciate them! you guys can really cheer me up when things aren't great!
