Thank you very much for your awesome videos!

    Thanks for offering the free lessons.All the students in the classroom don't have same capacity or the level of interpretation of the instructions within a fraction of a second.There must be a couple of seconds of interval during the instruction.The students must have sometime to interpret the instructions,put them together and frame a concept.The teacher proves his excellence in fast solving the problems but needs to review the way if he has been still teaching.It is sure to add one more feather on his hat.

    • @FortBendTutoring

    Hi Mr Whitt!
    I have a question about example 4.
    When we are done with factoring and then when we start simplifying,
    Why cant I simplify the denominator 4 with the other denominator 12?
    Is there a rule that doesn't allow simplifying the denominator of two fractions.

    • @FortBendTutoring
      @FortBendTutoring  9 лет назад

      That's correct. You can't simplify (as in cancel terms) horizontally.

  • @ryashairuna3838
    @ryashairuna3838 10 лет назад

    Somebody asked this question already, but mine's a little bit of different. On your first example, you cancelled 3 and 6 then went to 8 with the 2. I would like to ask why didn't you cancelled the 3 to 9 instead of cancelling it to 6? And what if since there's no "2" if I cancelled the 3 to 9, then I won't be able to cancel the 8. Will the final answers change?

    • @FortBendTutoring
      @FortBendTutoring  10 лет назад

      As long as there are factors that can be simplified diagonally or vertically, you can continue to simplify the problem. Both ways will work just fine. If you simplify the 3 and the 9 first, you can then simplify the 8 and 6. The result after multiplying will be the same.

      After understanding the steps, pause the video and work out each problem until to you get stuck and then play it to see what step is next. Keep using this process until you are able to completely do it yourself.

    I need a problem where when I factor I have something like this 8a(1-3a)(3a+1)(2a+1)/(2a+1)(3a-1)(3a+1) the answer I was given is -8a\2a+1

    • @FortBendTutoring
      @FortBendTutoring  10 лет назад +2

      They took the factor (1 - 3a) and factored out a -1 which allowed them to rewrite the numerator as -8a(3a - 1)((3a + 1). From there, you're able to simplify like the problems in this video.

    I know you keep repeating it, but I don't get why you can't cancel out the x or y in answer.

    • @FortBendTutoring
      @FortBendTutoring  9 лет назад +1

      You can't cancel them out because the numerator and denominator aren't the same. Also, due to the fact that the x's and y's are not being multiplied together in the result. Check out this video for further examples: ruclips.net/video/zBjjL-17ItU/видео.html

    I feel like problem #4's answer should be m-5/1 or m-5
