  • I've got a 1-Question test on this in my Algebra 2 class tomorrow. Either a 100% or a 0%. Hopefully this can help me out a bit! Thanks!

  • i cant get more than 60% for math...but i think i can get more for the next exam..^_^ thanks ya~

  • when you completed the square why did you add b^2/4a^2 to the left side but on the right side the 4a isn't squared? shouldn't they be the same?

  • wtf he just explained how the quadratic formulae come about.

  • why do you "throw the extra stuff (b^2)/(4a^2)" in?

  • Awsome dude thanks

  • Thank you. It was very well explained. Got extra credit points because of this! :D

  • amazing! mathematics genius!
