      @daviemeister3355 4 ปีที่แล้ว +25

      Yeah, I severely hate when that happens! Its not that I dislike those teachers... they are really nice! The problem is that their accent does not just suit the job in which they are teaching! Are we all so for diversity that we forget that its not about how diverse the teachers are but how they get the point across to the students? I am doing quite well in advanced functions right now.. I had a teacher with terrible accent, so not only do I not naturally understand her, but I naturally tune out when its impossible to comprehend. I had to search and search on my own, just to keep up. I just hope you were able to do well in that class...

    Thank you SO much. At first I thought you had to plug in every single factor to find all zeros but then I realized from your video that I only had to find one zero from plugging in and then use that zero and the quadratic you get from synthetic division to find the rest of the zeros.
    I have a test tomorrow and this made me feel so much better, again thank you so much please never stop making these videos.

      That verse is taken way out of context. Matthew 7:7-8 “Ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you."
      The context here is clearly that of salvation, NOT that of wordly riches, or assessment understanding, although God may provide such knowledge if He so chooses to.
