Frikimaths: Maths lesson (17.01.10)

Hello class first i need to say that i posted this so late because i taked so much time to find how to post this... XD. First we have corrected Mario´s homework. For Example: 3/4x^2+4/5x=0. It was a easy one.
Then we have done some second grade ecuations in class with Mario´s help.
Examples(here we needed to clear x and x+1) (exercise 75) : x^2-(x+1)^2=567
x^2+2x+1-x^2=567
2x=566
x= 283
x+1=284


I dont know more to post so this is all, i don´t know th homework beause i forgetted the agenda in class XD. See you next time!
