  • thx man..im passing my quiz tomorrow :D

  • Watchingyou was my Homework... no really, it was. Best HW EVER!! XD

  • how about 1 over x'squared - 1 Minus 1 - x over x'squared + 4x +3 ?

  • I love how he says I know it looks like you arent doing much here! I hate math

    I like this video good stuff.

  • OMFG THANK YOU! No more 64%s on my tests anymore :)

  • @yachiruvicecaptain it should be (x+2)(x+3)

  • @jackwcps when you expand (x+2)(x+3) it gives x^2+5x+6

  • @yachiruvicecaptain x^2+5x+6=(x+2)(x+3)

  • Thank you! You are so much better than my fat ass math teacher that is ruining my GPA because it doesn't feel like teaching.

  • in the first problem at the end you can factor out an x in the numerator, should you do it or leave it like that?
