Synthetic Division

[XBlades]

Wow this was much easier, it’s been awhile since I did this for trig / precal days. This is nice. Thanks for the refresher!

[OutFall]

I want to thank you! This is the quickest and simplest way this has been explained. I've gone through so many 10 minute videos that are extremely confusing. Your video is the only one I actually understood and was by far the shortest. Again, Thank You so much!

Makes me forget how much I miss math classes

[mattstakeontheancients]

Where was this guy when I was studying for the ACT. I actually enjoy these videos and have learned quite a few tricks

[antoniomonaco]

in italy this is the ruffini's rule and I dont get why most of my classmates find it so confusing, i think it's brilliant!

[abocado]

I’ve been trying to find this type of video for a while bc idk how to get the final answer of my problem but now I do!, Thanks so much (your a lifesaver!)

Thank you Master! These shorts are really productive, time saving and cool at the same time for someone like me in their learning phase and preparing for competitive exams And I really appreciate the efforts you put into this. Please continue your work

[devplasna]

A concept that I thought would be hard to relearn after months of not touching it was reexplained to me in less than a minute. Thank you for your great work.

That's damn cool!
We were taught long division and it's a pain

[henrylee]

Thank you so much. I stared a summer course today and the second there was something that wasn’t covered I searched for your channel

[noedeverchere]

It's actually called the Horner method 😊. Very useful for factoring. In general, a good way to get the first root of the polynomial is to search an "evident root" . Here it was 3, so we were able to proceed with Horner's method.

[Chaitanya]

Yes, Cardon method is good to solve cubic polynomial fast...

[benjiusofficial]

Our calculus professor came to us one day all excited because he had just learned synthetic division and he wanted to show us all for partial fraction decomp for Taylor Series. The whole class was wow'ed by something so simple.

[lawrencejohnson]

Love these! Before it’s all over, I am going to formally enroll and complete all the mathematics I struggled with as a young person.
This is so inspiring and enlightening. Thank you for producing these shorts, please keep it up!

[wilberforcek]

Wow I like this better than what my teacher taught me!!

[henkyagusleo]

The numerator is simply (x-3)^3. So it follows that the division can be reduced to (x-3)^2 = x^2 -6x+9.

[Mathewulf]

In Brazil we call it the Briot-Ruffini method

[yanitachristin]

Woowww! Such a great help. Thanks Mr Hu!

[TodayIsPresent_]

This is amazing; even though I don’t know why x-3 can be zero, especially it is a denominator; I was taught the denominator cannot be a zero, yet it is so cool to learn a new way like this. In the past I just thought it would be like (x-3)^3, so the answer is (x-3)^2.

Synthetic division is extremely useful, thank you for covering this!
