thank you! my math classes never taught this, yet these problems appear on tests. the education system sets us up for failure, but khan academy is our saving grace.
Jaskaran Singh i agree. but everyone has different preferences. even if his voice did irritate me, I'd still get over it and appreciate the video for its content
Math has always scared me because I've always found it so intimidating. But whenever I watch Sal's videos he has a way of making math seem fun and exciting. A rare gift indeed. My anxiety seems to disappear as he so calmly explains the steps. Thank you for making math fascinating, sal! Your videos have changed my entire perspective on math.
The best thing to do is to take a deep breath and slow it down. Most times people freak out and panic, preventing themselves from doing something that's well within their capability.
OMG I was struggling like one hour with one problem like the one that you showed in the last minutes . After that, I finished my problem in one minute. You're really awesome.
THANK YOU BASED SALMAN KHAN! For the longest time since high school, I had extreme trouble dealing with polynomial long division and once it again, it came back in Differential Equations (when dealing with partial fractions). Your video finally gave me a full understanding of how to do this! Thanks again! :)
I always find myself searching your videos after my math teacher's ATTEMPT at showing me. I don't know where I would be right now without you and your videos. So, thank you for making my life a little easier. sincerely, confused math studentttttttt
As someone in a college Math 42 class taught by a teacher that moves through material quickly and offers little help or mercy, these videos and the content on the Khan Academy website may be enough to turn the disaster that was the first 3 tests in the class around. Very glad I was referred to this.
Lol I also have a test tomorrow, and I kinda need to get my math grade up for this quarter so that it will bring up my semester grade which will maintain my year grade which combined with a dew other years will be viewed by colleges and majorly discount the price if I get a scholarship, and if I dont I may not be able to go to college or at least the one I want to go to which means I might not be able to fulfill my career :/ so no pressure
Really helps! I used to despise algebraic long divisions but now I go into my class and do the same sums I previously used to hate rather than complete my homework.
Describing it like long division was really confusing to me. Haven't done long division since 4th grade so I you lost me there. But when I think of it my own intuitive way it makes sense and I was able to do the problem in seconds.
I do online schooling, and a lot of times the assignments (at least the math ones) come with somebody doing a few examples, but the one I'm on right now didn't. I'm a visual learner, where I have to have somebody show me how to do something instead of just reading it. So, these videos have really helped me learn this when my assignments couldn't.
This is magic. My teacher, friends and maths tutor couldn't explain this too me with me understanding. But when with your video I learnt how to do it half way through like 6minutes! Praise you Mr.Khan
Hi Mr. Khan! I just want to tell you that I got a 100% for my test. I was missing out in class by a lot and I watched your videos and got perfect for my second quiz of the year. I got a 10% on the first test, but after watching your videos I got a perfect score on the second one! THANK YOU SO MUCH... YOU'RE THE BEST!!!!!!!!!!!!!!!!!
Mind-blown. It really helped that you showed it from the very beginning in simpler terms and then show what you found after by putting it back into the original, especially cos i was commmppllleetteelllyyy unaware of that division method until today...i just put the remainders next to the digit (which i tried to apply to this and failed miserably) xD I spent a good portion of today in confusion and mild despair at the first bloody chapter!, feel a bit better now that i've understood this v_v'
Thank you so much for providing your math lessons free of charge! They are helpful to so many people, including myself, and I think I can speak for us all when I saw that they are wonderful!
wow...I THANK YOU VERY MUCH!.....i won't pass my 3rd quarter exam if it wasn't for this!...I missed my lesson due to the event i was in to my school...but...this video make me catch up to where my teacher left us!...THANK YOU VERY MUCH!
The thing about math for most people is that you won't. The main purpose of teaching so much math in school is because it teaches you logical problem solving, which is something that will REALLY benefit you in the long-run. Plus, colleges love someone who's done well at math :)
MY GOD I SWARE I HAVE LEARNT THIS FROM YOU THAN FROM MY TEACHER AT LEAST YOU SHOW US EVERY THING WE DONT KNOW MAN I THINK I WILL GET IN 90S THIS YEAR BECAUSE OF YOU SALMAN KHAN I WILL TELL EVERY FRIEND OF ME ABOUT YOUR CHANNEL
Studied Polynomial Division at college today and really did not understand it, after watching your video I understand it completely and actually enjoy solving the equations. Thank you
This is brilliant. The only thing I'd critique is the expression that "x goes zero times into four" at 4:32, which is not actually the reason to stop there, besides the fact that it's not true (x goes exactly 4/x times into 4) . The problem is not that the algorithm doesn't "work" anymore, it would still produce accurate results even if the narrator continued. The problem is only that from that point onward, the algorithm isn't simplifying terms anymore, it makes them more complicated. This is why we stop there and just write "4 / (x + 1)".
I recommend trying to solve the equations yourself after the first one if you can't get it right check what you forgot to do by continuing to watch the video. It helped me and I got the method in the first watch! 😁
Thank you so much I was preparing for my exams and I just couldn't understand how to divide algebraic expression and now I understand and I find it easy thanks a lot
Thank you very much for helping me out. By the way, can you make a kind of research video on this long division and include the division of both polynomials and numbers? That way I would understand the true essence of division. And it would also make my logic regarding this polynomials' division more clear.
It give me extra knowledge and more confident to face any long division problem. If you don't believe me, ask me any questions from Division Algorithm for polynomial. I'm ready
There is a technique from Vedic Math called "Division on the Flag" that allows you to divide any degree polynomial by any other polynomial and write the answer directly in about 1/10th of the time.
In the last week example, when you divide the higher degree polynomial by the quadratic equation, why, when you multiply the 1 in, (x+1), with the 2 in, (3x-2), it the two a positive and not negative as illustrated.

Alberto Garcia why do you think that?
Alberto Garcia fair argument. Sal can't really change his voice though. And the slow teaching helps a lot of people.
his voice is good and never irritating

@Alberto Garcia you suck big. Give the guy a break.
I'm gonna thank you in my graduation speech!!

I bet it is good
"lets do another one of these. They're kind of fun!" ~rewinds video to make sure I heard that right~
me-
lol i thought the exact same thing
We all agree that no one likes polynomial division. YAY
I just kinda paused the video and was like: hol up
But it is fun :D
I've always strugged so much in math and these videos are saving my GPA! I learn so much more from these videos than in the actual class.
HOLY SHIT I FUCKING LEARNED HOW TO DO THIS IN A 12 MINUTE VIDEO BUT COULDN'T FOR 2 WEEKS IN A 40 MINUTE CLASS
Forreal thats exactly how i feel. My teacher blows at teaching.
preach it bro

Exact same for me!!!
still don't get it im doing it a different way hahahahah *laughs then cries*

But generally they could help. There is no perfect method of teaching so it's okay if you don't understand...

hey man, how’s life now :)
I was never good with long division... :/ So many steps to remember, at least for me.
SAME BRO, SAME
Thought I was the only one who just never remembered how to do this...
It isn’t really an intuitive process.

3:20 thank you for clarifying the minus thing, it made all the difference!
What I think about in math class "I'm gonna watch a khan academy video in this" these vids are a great blessing for all of us
This man is a true hero. Publishing all this great knowledge, for free. Man's a saint.

3:57 "6 minus 0 is nothing" Makes total sense
This guy makes math way easier.
Thanks man I have a test tomorrow and I can't learn from my teacher. This is still frustrating though
So.. How did it go?
We want to know how it went
Think about how insignificant that test was compared to now.... Either way, I hope you did great

2 days from a calculus exam and I learned long division in 5 minutes after not having done it in over 10 years. Sal is amazing as always.
Really helps! I used to despise algebraic long divisions but now I go into my class and do the same sums I previously used to hate rather than complete my homework.

I'm legit crying right now. I'm going to pass my math class now. Thank you SO much, Sal.
Did you ?
Well???
This is so much better than Biju's. I have that app in my phone and still I am looking at Khan academy to clear my doubts.
Thank you Khan academy ❤️
Yo this makes so much sense! Thanks so much! I thought I was going to fail my test tomorrow for a second.
