quadratic equation, a new thing to now..

after the inequalities, we now proceed to solving equations about quadratic equations.. yes it is very hard. there were lots of things you need to know first.. but as i continued...

pheeww.. so hard.. we learned about solving the quadratic terms in many ways, factoring, extracting the roots, and using other methods..

it is quiet hard but i enjoyed our activity last friday. hehehe.. we made a perfect square from an equation.. it was so exciting!! hmm,, from the cutting of tiles, then plotting them on the illustration board and draft the square.. uhhm, from that equation i added 9 one-tile with the measurement of 5x5 units.. pheww...

i really enjoy that activity ;))
