    My #algebra lesson for solving absolute value equations that involve two or more absolute functions.

    Absolutely love your teaching style.I personally never really understood why i did what i did with absolute value and you just seem to explain every detail about it in such a great way!! Thank you for being a great virtual teacher!!:)

      He calculated it earlier by comparing each absolute value term to zero. Watch it again and you'll eventually understand why it is for.

      Hello again i have a side question, 26:00 , the example , i have been solving some of those like that, first solve them as a equations and then use their *roots* to be an some sort of a turning points etc, and checking intervals between them just like u did, well i`ve succeed to do so, but i found some examples witch have no roots , what do i do, how do i solve the inequation if it has no roots.
      P.S. i thought well if there is no *roots* well then this is either every single x or no solution.
      it worked for my example that i was stuck in.

    Thanks a lot for such nice video's. So well explained. I was able to apply this logic to lot of other problems but failed to applys inequaity |7 - |4 - x|| >11. This is a abosulte value within an absolute value. Can you please help me with this one?

    • @profrobbob
      @profrobbob  10 років тому

      I wish I could help. The type of problems I did in this lesson are not in any of the high school books I teach from, but I have been asked about them a number of times. I did some searching to figure out how to solve them and this is what I came up with:) I am not sure if the methods I discuss here are the quickest method but they work. I did not see any example problems like yours?!

    • @sanjeevnarula3781
      @sanjeevnarula3781 10 років тому

  • @xxpupexx

  • @yarubik
    @yarubik 7 років тому

    In the second example when solving for the first interval, why did you have to multiply the whole equation by -1?

    • @beophobic9653
      @beophobic9653 2 роки тому

      It’s often easier to solve polynomial equations when the leading coefficient is positive. This is not necessary, but rather preferable.

  • @MyThundermuffin

    Hi professor Rob
    Is x|5x-1| the same as |5x^2 - x| ?
    Also could squaring the both sides method work for example 2 ?
    Awesome video btw :D

    • @profrobbob
      @profrobbob  9 років тому

      MyThundermuffin You cannot distribute through the absolute value symbol so x|5x-1| are not the same |5x^2 - x|. To answer your second question... I do not work with these types of equations in my high school math classes. I made this after some research to answer some common questions I was receiving. So, I will say that I do not believe your squaring of both sides will work.

      Yeah...I mis-copied a number. It is not a critical error because it was not carried through the rest of the problem, but annotation corrections cannot be seen without Flash. So I made a correction and reposted it, but the monetization filter is questioning if the new video is actually mine! If this video is not approved for monetizing this will be pulled eventually instead of the other one:) Thanks for watching and letting me know!!!
