@mrnarason Maybe a more detailed comment could enlighten me. You obviously have some problems with the video. I know the resolution is not good and I will repair that, but what about the content?
surely, there has to be a more efficient way than testing the factors. the problem presented was simple, but if you are dealing with large numbers with many factors, you could be testing all day
@ScrewAttackChina You're correct in that, now, there are more efficient ways. A Graphing calculator gives you the answer in a minute or so. Calculus would also help, but that is beyond this video. This method assumes smallish numbers and no calculator avaiable.
Comment on the video. A bunch of us teachers are trying to help, while comments like this are why Youtube is being banned from our local schools! Grow up!
Wow. What luck I came across this video! =] I'm in Pre-Calculus learning about end behaviors and critical points of graphs (e.g. x^3 etc....). This helped me factor those kinds of equations. Now I can find the x-intercepts before my teacher teaches it to me. Haha. Thanks.
Oh shoot man I didn't know that! Sorry for being kind of rude. :( Just looking out. I guess I should have paid more attention to this video before baggin on it for no reason. Sorry again.
WRONG WRONG WRONG WRONG WRONG. You don't "plop an x out in font". It's actually (x - 1) as one of the factors. If you use +1 as correct number to go into the division, change the sign when using the actual facorization!!!!!!!!!! DELETE THIS VIDEO.
Actually there are two methods that I have seen teachers use. If you ADD in the synthetic division step then you have to remember to switch the "+1" to a " - 1" to get the factor as you have stated. However, if you SUBTRACT in the synthetic division step as I have in this video, then that is not necessary. If you are working with " + 1", then you get a factor merely by "plopping" an "x" out in front to get "x + 1". Thanks for the interest, but I will not be deleting the video 1
Hi, I thought '1' was the root of the whole polynomial equation? If so, shouldn't it be (x-1) since x=1 instead of (x+1)? Your answer is absolutely correct, but I still can't figure out why... Thnx. Btw, this was a life-saver!
In our curriculum, students must know how to do this by hand as well as by using a calculator. Synthetic division is ON the curriculum, so we have to go through this step by step to show them how to do it. If it is "so easy" for you, then great, but I know from experience that it is not that way for most.
(-6 - +6 = -12) what confused you is he wrote positive six as +6 although he subtracted, just as i have done in the in my equation above.. :D hes good to go!
This was really helpful. Thanks!!!

@AtomicHercules Yes, I agree, I am going to redo some of the "poorer" ones.

Although I prefer mental math, there is definitely a place for a graphing calculator. I do not understand your comment.
