JG, how I wish I know u in person. I really find it extremely difficult to describe how gifted and important you are to humanity! Please, continue with this good tutorial work bcos generations unborn that are yet to come will also watch these videos and keep thanking you forever! What could be more than that? We deeply hold you in high esteem bcos you've been doing what our lecturers and Professors couldn't do for us while at colleges and universities. Thanks man!!!
tip: you don't need to solve all 3 regions, just solve the one on the left. once you solve it, then the region to the right will always be the opposite sign of what the first one is and so on
thank you so much. I hate math but I always feel excited when I finally get the answer right, and this video helped clear things up for me so that I could get there.
MR. Organic Chemistry Tutor, thank you for a fantastic video/lecture on Solving Polynomial Inequalities in precalculus. These are strong analytical tools for all levels of science and engineering.
my calculus teacher completely skipped over learning this in class and even included it in the review for my test coming up. Thank you, you've saved my grade!
Our exam will be conducted tomorrow and im struggling in solving polynomial inequalities but look what I have found. Thank you for this video. It really helps me a lot.💖💖💖💖
Omg you are god gifted I wished I had a teacher like you 😑 My teacher couldn't explain this in a whole damn week And you just made me learn this in just 12 mins 🥺🥳🥳
What happens if your factors are the same (and are less than zero) and it's NOT also "equal to zero" (in a "less than" situation, or vice versa)? (x-3)(x-3)
She didn't specify the use of the term "test numbers" which are the numbers inside each interval that was created using the zeroes (or whatever number amounts to the inequality equaling zero. In this case, the zero would be 3, and the interval notation would have to be (-infinity, 3) because if you take one factor of the above you have x-3
I appreciate your videos so much since I started watching your videos my math grade has shot up and the only person I can thank is you keep up the good work
For the last problem, isn't it x=-1 instead of x=1, because when you do synthetic division you're putting the "h" from "x-h" on the upper left corner, so in this case where we have 1 as our "h", wouldn't it be "x-1" and to solve for that value of "x" we had we just set "x-1" to 0 and solve from there, so it would turn out to be "x-1=0" which turns to "x=1".
You assumed -h is being used in synthetic division accidentally. x-1=0 so we use 1 in synthetic division. Same goes for finding the roots since the root is the number being used in synthetic division if it's not an imaginary number.
After finding the points where y is 0, I graph it and it is much faster. You just have to be familiar with the graphs and plot the points where y is equals to 0 only. Works better for me.
What he means by that is the behavior of each zero. Since they are all one, they go straight through the x axis each time, which also means that the signs alternate

Please can you like make a video playlist of all your videos on subjects respectively
THIS GUY IS SO GENEROUS
IT IS BECAUSE OF PEOPLE LIKE HIM HUMANITY IS ALIVE
LOVE YOUR VIDEOS
True😊
Facts..
I am GRATEFUL 👍🏽🙏🏽
you explained to me in 12 minutes what my teacher couldn’t explain in 90 🙏🏼
I spent an hour with my college textbook and you did in minutes what it couldn't do at all. Thank you!
He explained in 12 minutes what my teacher explained in 2
Thats why we see yt
facts
At least your teacher tried... We ran out of time so she just gave us our worksheet with 11 of these problems
You have saved my grade in math so many times- thank you from the bottom of my heart for doing what you do
I have an exam in half an hour and I'm trying to relearn everything because I didn't understand the first time. Thank you for this!
How did it go ?
@@Yahoooo.1From the time you asked, he had given that exam 2 years ago, he would hardly remember the result 😅😅
@@ShauryaBaloni73 bro probably graduated lol
It's the best tutorial.. thank you

how much quicker i learned this from you rather than my own teacher is crazy
tip: you don't need to solve all 3 regions, just solve the one on the left. once you solve it, then the region to the right will always be the opposite sign of what the first one is and so on
I’m gonna comment on this so I can remember
You can also solve the one on the middle or the right too the right might be easiest
Another tip: sometimes inequality can have more than 3 sections. Just make sure you solved all your roots, then you can assume.
i always check 0 and then one of the regions checks out
Can you prove it? Generally. Not with examples! 🙂
thank you so much. I hate math but I always feel excited when I finally get the answer right, and this video helped clear things up for me so that I could get there.
omg same
Your videos are so underrated! I hope a lot more people visit this channel
i didnt understand what my teacher said for a whole damn week and u explain this in just 12 mins 🙂💀
thank you 🥲✨
love your videos. You make learning precalcus easy !! I should pay you instead of my professor
ive been trying to do these for 2 weeks, 2 videos anf boom ik it all
Ur a blessing to my Math CA's
MR. Organic Chemistry Tutor, thank you for a fantastic video/lecture on Solving Polynomial Inequalities in precalculus. These are strong analytical tools for all levels of science and engineering.
this makes so much More sense than how my teacher taught it!!! thx
my calculus teacher completely skipped over learning this in class and even included it in the review for my test coming up. Thank you, you've saved my grade!
Yeah, aren't they assholes? That's actually fraud, and you should use that word.
An amazing teacher! You make everything appear so easy! Thank you soo much
THANK YOU FOR SAVING ME I HAVE A TESt ON THIS TODAY AND WATCHING YHIS VIDEO RIGHT BEFORE TRULY HELPED ME SO MUCJ MORE THAN MY MATH TEACHER EVER COULD
Always struggled with this concept, but this really simplified it for me!
This is better than any math teacher I have ever had
You always explain it so well. Awesome tutorials.
And finally I got the concept.....thanks!!!😊☺
Pre calc final in a few hours. Can’t sleep.
Always kno I csn find info here, well explained and accurate. I am thankful, man.
Thank you very much, Julio! Your videos are incredibly helpful! Keep up the great work!
Thank you sooo much you saved me with my math exam! 😭😭
Our exam will be conducted tomorrow and im struggling in solving polynomial inequalities but look what I have found. Thank you for this video. It really helps me a lot.💖💖💖💖
Omg you are god gifted
I wished I had a teacher like you 😑
My teacher couldn't explain this in a whole damn week
And you just made me learn this in just 12 mins 🥺🥳🥳
I'm from Ghana in Africa , I wanna say thanks for your good works , you've made me simply impossible to understand ❤️🙌
Impossible to not understand
You just saved me from a monstrous exam. Thnx
Thanks for saving my interest in calculus like inequality , domain....
is this done in calculus in college? I'm in high school and I'm doing theese. now i feel a little more confident
@@f.a3202 not really
Thank you so much for your videos, they are the bests ones ever!!!!!
you just made the hardest thing on math look very very easy THANK YOU!!
Dude the hardest thing on math
Seriously?
Give this guy a medal.
OMG I FINALLY GET THIS NOW THIS MAKES WAY MORE SENSE TYSM
Teachers take hours to teach us this and this guy teaches us in 12 minutes clearer than any teacher.
Bro thx ur the best my doubts are clear i found the answer at 5 am but it is what it is love u :)
I didn't even need to watch the whole video to have a better understanding of this topic than what Aleks could provide
THIS GUY IS THE REASON I AM PASSING MATHS!
This video is so helpful you explained it better than my teacher did. thank u so much!!!!!
9:50 How did u divide like that??? I only now long division help pls.....
Thank you I understand your explanation 100x better than my teacher. Probably because she tried her own video instead of giving us a video.
you just saved my math grade!!!
And my life from being beaten by my Asian parents
Ahh yama muli bakulekafye , Amano too much, imwe fyonse mwalikwata data. Jahman juice mwemfumu jahman juice. Imwe takwaba ukumichila tata. Keep up the great work.
Thank you! I had a tiny moment of panic when I forgot these and feel much better now
keep up the great content
I am really appreciate your explain ❤ thank toct
Bro you ducking saved my butt i got a math test and it’s like 12 thank you
W końcu znalazłam przykład który mi pomógł bardzo ❤
What happens if your factors are the same (and are less than zero) and it's NOT also "equal to zero" (in a "less than" situation, or vice versa)? (x-3)(x-3)

In this case, the zero would be 3, and the interval notation would have to be (-infinity, 3) because if you take one factor of the above you have x-3
In factoring by grouping, what if the groups we're left with aren't the same? I ended up with x^2(x+10) - 1(11x+180) from x^3 + 10x^2 - 11x - 180
You’re a good man, thank you.
You are the best this is well explained
I appreciate your videos so much since I started watching your videos my math grade has shot up and the only person I can thank is you keep up the good work
Very good technique and explaination.
Thank you so very very much for clearing up this concept for me! You are a Godsend!
Hello,
@ 3:33, why is the answer "or" and not "and"? Doesn't the union sign in the interval notation mean "and"? Thank you.
I forgot, and this video helped me. Thank you so much!
🙏 I have stepped into the light
Way better than what my professor taught me.
You have solved my all doubts in first 4 minutes, lol. Thanks
Thanks you so much, I might just start my own YT Channel doing the same! you are really great at what your doing!
Thanks for taking the time to explain to us. Neatly explained
my brain cannot handle this🥰
Thank you so much!!! now I’m ready for my test:) thank you
You are a legend thank you so much
At 6:09, are you using the zero product property to get those answers?
I'm very grateful, you have done me a lot of good things, I appreciate 🙏🙏
Great job man! You're wonderful!!!
It's a woman bro.
OMW THANK YOU SO MUCH!!!GOD BLESS YOUR SOUL
Your better than my professor
Thank you!!! You have helped me a lot!!!
Great teacher!
Thank you so much. This really helped
Thank you so much! My teacher did such a horrible job explaining this! But you were fantastic

For the problem at 8:45, couldn't you use the grouping method
Thanks u so much u are a great math teacher
I finally understood this after a week in school
You make very helpful video for initial
U saved my life
Your video is on point. Thanks a lot .
I wish if I had watched any videos from u
Am a student at MALAWI polytechnic
I love your videos and I succeed coz of them
Amazing video, thank you!
Thanks for the info!
Thanks great video solved my all doubts
After finding the points where y is 0, I graph it and it is much faster. You just have to be familiar with the graphs and plot the points where y is equals to 0 only. Works better for me.
I do the same
Your a life saver.
Very nice from yadwinder singh .
6:45 please explain multiplicity and why does the middle have to be positive.
What he means by that is the behavior of each zero. Since they are all one, they go straight through the x axis each time, which also means that the signs alternate
GENIUS! THANKS A LOT!
wow u are really good man ..keep on uploading more videos
Thanks so much this is so helpful!
not to be dramatic but you kinda saved my life
can someone tell me why the sign doesn't change when the multiplicity is even? pls 11:40
thank you sir
Helped!! Thank you!
omg this is so helpful
Great content 🙏🏽
