    Last year, your videos helped me pass one of the hardest Math classes of my life and I passed! I was able to transfer to Culinary school to pursue my true dreams and I really enjoy my new school now. Thankyou so much. Your vids change lives!

    Hello, I appreciate your video, but I have a question on why you subtracted 32 at 4:34. Why couldn't you add 32?

    • @linahdiaz8704
      @linahdiaz8704 5 років тому

      Cause you have to cancel it and you cancel by subtracting in both sides

    What happense in insted 16x you had 18x? In other words what shell we do when you try to write half of b, which will be 9 and undevideble on 2?

    • @gdkiantheboss7664
      @gdkiantheboss7664 8 років тому +1

      You can still divide 9 by 2. It's okay if it has fractions.

  • @tjbjsb

    I know where the 32 came from, but why add and subtract on the same side?

    • @dalilaguillen7
      @dalilaguillen7 7 років тому

      tjbjsb I think it's because the rule of what you do to one side you do to the other can't apply because we want y to be alone

    • @ti84satact12
      @ti84satact12 6 років тому

      Because if you add 32 and subtract 32, you really haven't changed the equation, although it helps get the equation into a form that allows you to complete the square..

  • @royalwilson6640
    @royalwilson6640 5 років тому

    OK in the answer (4, 49) where did the 4 come from ?

      Ekaterina Tavadze Melin Grouping (doesn't work with all equations), depending on the exact equation using the quadratic formula might be easier.

    (X+1)^2+(Y+5)^2 =25 How do you get the pair and say if it is a function or not from this?
    Where can I find this lesson and also: vertical stretch, reflection, aces of symmetry, even odd functions, graph square root functions.
    I understand your way of explain , I have being following all your classes. I hope you respond!!!!!

    Confused on why -3 multiplied by the +4 gave you +12, shouldn’t it be -12?

      Not possible as it is not a parabolic curve but a straight line... I hope this is right
