  • @300melody Did you get that A? Please, be honest.

  • act prep:)

  • Thank you! I'm an adult who hasn't done this stuff for at least 15 years and the way you explain things is very easy to understand. I think I will finally pass the algebra portion of my college placement exam so I can finish getting my Associates in Arts degree and move on to nursing school. Excellent teacher!

  • @jamesusespivot that is also correct, it doesnt matter what order the double bubbles are in. If you want to check your answer after a reverse-FOIL just FOIL the bubbles you made and see if it matches the question.

  • yay i'll get an A on the 7th grade final :D

  • at 9:52 i had (x-13)(x+2), that's correct aswell, right

  • lol KFC

  • Thanks for the awesome video! I'm working on upgrading my math after being out of high school for a few years, and this video is a great help for what I'm working through now.
