Dividing polynomials using long division

- 👉 Learn how to divide polynomials using the long division algorithm. To be able to solve a polynomial, we need to be able to get the factors and hence the zeros. To get the factors, we use the rational zeros theorem to get one of the zeros and hence one of the factors and then divide the original polynomial with the factor obtained to get the remaining factors.
To divide a polynomial using the long division algorithm, we continuosly divide the polynomial (dividend) with the term having the highest power on the variable(s) in the divisor to get the quotient. We will then multiply all the terms of the divisor by the quotient and subtract the result from the dividend. The result is divided again by the term having the highest power in the variable in the divisor to get another term of the quotient. This process is repeated until the term having the highest power of the variable in the divisor can no longer divide into the dividend.
The result after subtracting the product of the last term of the quotient and the divisor from the remaining part of the dividend is the the remainder when the divisor divides the original polynomial. If the remainder is zero, then the divisor is a factor of the original polynomial.

This man is the only thing preventing me from failing all of my math classes. You saved me and highschool and you're saving me in college. Thank you!!!!
So happy to help you out!!
lmao 10 years and the same guy

OMGG SAMEEEEEE I LOVE HIM SM HE REALLY HELPED ME GET A B
there long divisions in college too😢
Long division is difficult with polynomials, happy to help, keep up the hard work
Brian McLogan life saver fr. thank you
What if the polynomial's leading coefficient is 3 but the 4x^2 isn't there?
@Jedidiah Malolo because some people get chemical equations and others understand algebraic. Just like some people understand long words like antidisestablishmentarianism and some people are good at learning multiple languages.
@@RageCannon-tf3ob might be a bit late but you have to add a “placeholder”. You would add a 0x^2. Just to keep the exponents in decending order with no skips.
@@izzie275 Graduated a few months ago, but thanks anyway. I was able to read the word coherently though
Its nice to see a teacher who answers students questions instead of getting mad that they didn't understand. I like your channel and you help me a lot thanks!
I always look forward to seeing your face the night before my math tests. Keep up the great vids!
😀 cheers!
Lol
@Andy lolz
same 😭
😂😂😂
stuff takes time, don't worry about it. We all were new to learning this stuff once before
Yessir!
Thanks! :)
I don't like math anymore
Brian.. you are the best teacher ever! Whenever I get stuck on math and find a video by you I understand it in less than 10 minutes! You are the god of the math teaching world and for that I pray to you 🙏
Finally able to understand this! My teacher never really explained where they got the numbers, so while I was always trying to figure out where a number came from, I ended up getting behind in the lesson.
Yep, teachers are often really smart so they don’t really explain very well
Hello Alex you can check divide of the polynomial in my channel also please watch once

I actually cannot stress enough how much students like me appreciate videos like yours that help better explain units like these!
thank you for your kind words, I know it's tough and frustrating trying to understand math at times. Keep up the hard work. I'll do my best to keep making videos for you,
Using this video in 2019. Thanks for helping me learn!
Your not the only one 😂
Using this video in 2020

Just wait for 2020...
Still using it in 2021
Im in college taking calc 2 and i’ve NEVER seen this until i got to integration by partial fractions. I’ve been watching videos on how to do polynomial long division and you are the ONLY one that made it make sense. Thank you!
I’m legit a 10th grader trying to learn this online. Life’s tough
@@robertm814 frfr, online math vids help a lot.
I'm in the same boat rn. Integration is tough 😅
@@robertm814 its one of the easier maths topics
Im in 11th grade and gonna do pre calc. Ive never seen this until learning slant asymptotes lmao. Im glad I found out about this guy from early, so I just ignored all the other videos and went straight to his
I feel you, I had a very similar experience. Long division takes time to sink in. Especially with polynomials. keep with it and let me know if there is anything else I can do to help you out
Brian McLogan i would like to say thank you this really helps
@@ComradeHoan Same
awesome, thanks for watching!
Mr. Mclogan am I awesome?
@@nebulai9587 yes :)
@@nebulai9587 bro what kind of question is that
10 years later and here we are, much obliged. I really appreciate the fact you explained how you got each answer, my algebra 2 teacher just expects us to know everything.
My teacher explained it, but... didn't do a really good job, then proceeded to tell me I "wasn't trying" lmaoooooooooo.
I was told as a child that I was "bad at math" because I had trouble learning new concepts (despite being very good with arithmetic) so I've developed mental blocks which make my brain shut off and my heart-rate spike whenever I see a sheet of paper with numbers on it. Watching these videos and learning in plain terms has helped remind me that I'm *not* "bad at math" and I just need to breathe in and get past my insecurities.
Thank you, Mr. McLogan. I'm more proud of the C I have in college algebra than any A I've ever gotten.
Love love your videos!! You are the reason why I’m hanging in pre cal. Teachers like you are very appreciated. Thank you so much!!
you are very welcome Jassmin! happy to be there for you!
You are my savior because I do not understand my trig teacher at all. You help me get a 100 on all my test. Thank you Mr. McLogan.
Thanks so much for the video, it saved me from my algebra 2 teacher who taught it poorly.
Me and my classmates have been struggling a lot with our current math teacher but when i watched this, everything clicked! Tysm!!
Taking College Algebra over the summer because of covid and we are receiving 0 instructional help from our teacher + she has the thickest Russian accent, so I am forced to TH-cam all of my sections for help and you, Mr. McLogan have come in clutch over and over again! Thank you
This is college algebra? This is commonly taught in beginner alg 2 usually, some advanced courses may even squeeze it into alg 1
I wish I was in your class 😭
Online class now.
Finally I can understand this, my teacher just does it on the board and doesn’t explain a thing and expects us to know it
its been nine years since the video posted but the video is still helping us.
Mclogan, man it’s been 12 years since you posted this. I’m in tenth grade, only been watching your channel since the sixth grade, but you’ve help me so much. I can’t explain how much these videos help my grade. I’ve been stuck on this topic for so long, and then suddenly a light bulb went off. THANK YOU SO MUCH.
I teach high school math remotely right now because of the Coronavirus. Your videos have been saving me so much time! Thank you!
I love your videos , I help my son with his Math and I watch these videos to clear my concepts - its like I am learning Math again after 30 years .. You make it so easy..
Wow even tho this video was posted 9 years ago it still helped out a lot. Thanks🙏🏼✝️
Because math answers can’t be argued and will always remain the same.
Algebra exam tomorrow… thank you!
omg, 2 minutes in and i was already understanding how to solve it. thank you so much!
I didn't learn long division when I was in elementary school because I had a disability. But I love re-learning things to get even more ahead in math, not just the subject but doing the same thing for other clases. I appreciate the help from this video Mr. Mclogan, it's actually easier than the way my teacher did it today it was a little confusing but, I'm understanding it now.
Your kids are SO lucky to have you as a teacher. Your method is so direct and effective
Thank you for your video Brian, from Nicaragua. I share your videos with my class for reinforcement
With online class and bad quality, it’s hard to focus on what’s going on, this helps a lot .
Love how you explain everything clearly and concisely. Sorry to my math teacher but when he explains, it's like he's trying to make someone remember how to do it, not teach someone who's new how to do it.
when you wrote 40 instead of 42 i thought my calculator is broken
Hello Brian. First of all I want to thank you for the excellent classes you have posted. I'm taking college algebra and many times I have to watch videos because I finished high school like 45 years ago and I don't remember everything. I'm doing my best but there are things that I forget easily because of my age. You make this class easier to understand. I wish you my very best!!
Dude. I never learned long division in school, and dividing polynomials was the first time I had tried it. Thank you for putting these up.
you are very welcome!
Really
That is why I do this, I want to make math education accessible to all. Are you going back to school?
Brian McLogan iqqrwwwewqrq
This is the only thing that has ever tripped me up in Algebra 2, thanks for helping me learn it better!
2020 and your old videos still help. You are a legend man thank you
For 2 weeks I have been struggling with long division, but the way you explained it just made it click! Thank you so much!
Thanks for giving me hope and motivation to keep going through these lessons!
Thank you for helping me out. Breaking it down easily by hold it places value. The professor doesn't breaking easily as you do.
Thank you for all your hard work sir! You're one of the biggest reasons why I can still keep my Math grades up even in modular learning
Thank you so much this method is way better than other methods my teacher’s taught in school 🙂
Taking AP Pre-Calculus this semester and I have my Unit 2 Test tomorrow. Your videos are the reason I do good in that class. THANK YOU!!!!
Doing online school rn and my teacher is teaching though khan academy. Youur videos help me process things so much better thank you!
So happy to be there for you!!
your videos help me so much because my professor isn’t the best at explaining things and so i’m often left to teach myself, but your videos explain things so clearly!! thank you!!
Thank you so much, your teaching is really a life saver for me when I go into exams
Actually the only person who helps me in my math class , and to be honest you help me to solve whole my confusion in lots of subjects.... * thanks a lot *
I wish I had this guy for math, he seems like a great guy
Thanks man you are the best ! I am a college student and I am studying for finals and your videos helped out A BUNCH !
Mr. Brian my goal is get prepared for my GED test I want to keep focus on the math part which I failed. So let's work on my algebra ready to focus. From your videos you taught me what I never learned in school thank you Mr. Brian I appreciated. I was bullied a lot in school while having trouble concentrating ( Teachers was teaching) I'm so happy to be away from Toxic people especially who think they know everything
10 years later, this video is still relevant. I needed a refresher
Perfect!
dude, you are such a good teacher you take the gibberish my professor tells me and make it understandable
thank you for this video makes math so much easier for me
This is absolutely confusing, but this guy explains it the best, I just need to take my time understanding it.
been watching since high school!! saving my life in college rn!
I got a A+ on my math test thanks to your video. Thank you so much 🙏🏻🙏🏻🙏🏻
You are one of the best gem youtube has!!!! THANKS FOR YOUR SERVICE!!!
Thank you so much for your wonderful videos... they literally help me pass my college algebra class... Thank You!
I did have a quick question.
Isn't -3x-21x = -24x... not -18x? Or did I do the math wrong?
@meez thank you so much 😊
God Bless you! Thank you for this! I'm here in 2024 and you're a big help!
you're the reason I passed math, thank you! its 2020, damn
No its 2021
There are a lot of kind of people in this world. Mr. McLogan is one of the few that are amazing.
You have no idea how much this video has helped me. My brain hurt trying to understand it and my teacher goes really fast… now I can actually understand and do my problems!! Thank you so much!!!
wow. he does a great job of explaining everything! i really wanna know tho, do any of his students use this 12 years later in their day to day life?? lol
The fact this was posted 11 years ago and STILL helping people is amazing
you just saved me hours because i took a jump from middle school to college stuff so I never learned some of this stuff and the course never bothers to show me because most people should already know
I've learnt the majority of Algebra 1 in like two weeks the dam long division method is the only thing getting me right
This was so helpful it refreshed my memory on this thank you so much
Is this what understanding math feels like???? Thank you thank you thank you
Math finals this week. This really helped!
Best of luck!!
@@brianmclogan Do you have a tip to remember to turn the things negative when subtracting
Your the only person on youtube I enjoy watching because you go thru it in such dept an that's saying a lot because math isn't my favorite subject.
This honestly feels like magic.
Learning from this video in 2022! Thanks for this.
Thanks so much trying to get in nursing school and math is stopping me but you’re helping me understand it so much better 😊THANKS FOR YOUR HELP
I think you just single handedly saved my algebra grade just with this one video
lowkey carrying my trig grade rn ty
once again he has done better than my professor
Thanks for this. I needed a quick recap in my final semester when the senioritis be hitting hard.
you made this so much easier thank you. The only part I got confused on was the 3x and 21 part but I think Ive got it down now.
This is helpful, thank you! Homeschooling my 9th grader in Algebra 2.
I had forgotten so much of my math. This is a great refresher course. Thank you Brian. 👍👍👍
“No..it doesnt make sense at alll.. “ girl shut up lol i cant be a teacher
Same energy here
this is great, I finally know how to do division of polynomials, you're a great teacher! keep up the great work!!!!
you are literally saving my math grade right now
you are always there with a video to answer my hard question by solving it easy and fast thanks a lot
never fails to get the point in my head , keep up the good work!!
won't lie, never thought I'd be in college trying to remember how to do long division lmao
Thanks from India !
Very welcome!!
12 years later, and this guy is still helping me with my math homework
Thank you for having these! They are appreciated!!!
Literally watching you while inside of my college lecture because you teach better. Cant believe im paying this professor just so I can sit and watch you instead
THANK you Mr. McLogan
petition to construct a Brian McLogan statue you sir are a legend
This guy saving me right now
I really appreciate your videos and teaching style. Thank you
Thanks 🙏 Now I have little idea on how to solve Polynomial long division.
using this for the upcoming SAT subject test! thanks for the help!!!
I really enjoyed watching this video because it helped me really understand how to divide polynomials and it felt like I was learning in a classroom again. Any questions I had in the beginning regarding polynomial long division was answered in this video and I now know how to solve these types of equations. I especially liked that you chose an equation that has a remainder so now I know how to solve any polynomial problem even if the remainder ends up as 0. Thank you for this great explanation!
