  • whats the application that youre using?

  • @nehhshstr I'm using Photoshop for the "white board" and markers, a Wacom Bamboo Tablet to write with, and Screenflow to record my desktop and then edit.

  • when you factored the second eq isn't it (x-1)(2x-3)(x+2)? cuz in your example u put (2x+3)(x-2) but then that would equal 2x^2+x-6 we want 2x^2-x-6

  • @wittydipkid1 Be careful. (2x+3)(x-2) multiplies out to 2x^2-x-6.

  • Would you happen to know how to factor 6w squared + 18w -15? I cannot find a solution....

    The overall problem is:

    6w cubed + 16w squared -21w + 5

    I found that (x-1/3) was a factor and used synthetic division to find 6w squared + 18w-15... I am now stumped.

    Thank You!!!! (Excellent Video!)

  • @alana8238458 You can only factor a 3 out of 6w^2 + 18w - 15. If you're trying to find the zeros of the polynomial then you can now use the Quadratic Formula to solve 6w^2 + 18w - 15 = 0.

  • should buy a voice muffler thingy to cut out unnecessary mouth sounds.

  • honestly they should take all the online teachers and put them in class rooms instead of having horrible teachers

  • Got an algebra 2 exam tomorrow soooooooooooooo tanx my teacher can't explain things like this

  • great video, get a drink of water!

    :P
