Solving Quadratic Inequalities (Precalculus - College Algebra 25)

[@chericha]

You are changing so many lives out there Professor. Thanks again.

[@tybargky3554]

Please never delete this channel. Thank you SIR!!!!!!

[@kayrauckilinc]

It is not easy to be a role-model for someone. You did become one for me. Thank you!

[@pankhuriagarwal2772]

You are finally back !! Was waiting from a long time.... Can't wait when you start trigonometry ❤️❤️ Stay Safe ! 🤗

[@Peter_1986]

I would say that Geometry is one of the most valuable prerequisites for Trigonometry, since Trigonometry deals a lot with triangles, the unit circle, and sometimes parallelograms as well.

[@jassimjaved3309]

Thank you so much! I wish I had a professor like you who taught this to me! The new generation is lucky they have these videos!

[@francistde_menace]

The world's greatest online tutor🤗

[@VacuousEyes]

Explaining difficultly with ease. Thank you Professor

[@tigerxuexue832]

Welcome back you legend!

[@rashedsayem]

Look who is back...Its Dwayne Johnson of mathematics, Prof. Leonard ❤

[@sandratingalay]

You are always awesome in explanation. Now, I m clear. In my college class, I feel like the prof asks without teaching which means she cannot make us understand of it.

[@adamalmir5214]

Sir, your the best. I really like how you dedicate so much time to making sure the viewers understand the topic and why it works. That’s the key to education. May God bless you for your hard work.

[@camofle6898]

Clicked video liked it, commented, left. Thanks for helping me get an A in calc 2!!

[@dougjohnson5487]

I checked everday for a new math video so today is special. Welcome back!!

[@gibsonowade8512]

Watching all the way from south pacific....You are super man in math teaching. I dont attend my lecture I attend to you. Thank you so much for your effort and time.

[@lionlynx7480]

Hi Sir!!, Just wanted to let you know that you're an amazing professor!! I've been having some trouble learning mathematics but here you are. The real life hero!! I salute you sir!!!! You deserve a billion subscribers!!! : )

[@leemayviljoen7402]

Dear Professor Leonard.Thank you for keeping making these awesome videos. Please keep making them! I've learned so much.

[@Andrea-su6py]

Wow he has 442k followers. I remember when professor Leonard first started he recorded the classes for his students and when he thought it was cool when other people from other countries would watch his videos. He was my teacher for Algebra I was upset when I went back to finish school and he wasn’t teaching at my college anymore.

[@bextrekks8354]

you were one of the students actually in his class! cool! This is an amazing teacher!

[@glitchpirate71]

>> he thought it was cool when other people from other countries would watch his videos And he was right. I'm taking his lectures from Italy (I'm Italian) as a refresher for a degree in physics.

[@rashedsayem]

Glad you are back ☺

[@p0intblAnkwaziT]

Professor Leonard, you mentioned that Linear Algebra was next on the playlist. I'd be more than happy to pay $,1000 + for an intermediate level statistics and other high-level stat courses too!

[@sinamaihami9006]

Thats my hero thanks for your awesome videos keep up the great work LEGEND.

[@georgesadler7830]

Professor Leonard, thank you for a brilliant lecture/video on How to solve Quadratic Inequalities using factoring and graphing methods. These videos are helpful for students all over the world.

[@unstablejumo8098]

You are to my college mathematics what Paul Hewitt was to my high school physics. You sir are a fantastic teacher.

[@alis5893]

THE BEST MATHEMATICS LECTURER EVER

[@mikem9270]

Just got my "Professor Leonard believes in you" shirt and "I'm bringing (1+tan^2(c))^(1/2) back" Decal 👍 love them

[@johanbaylosis]

This is way better than the study pug ad that keeps popping

[@janithavidunath]

I have watched your Calculus 3 lecture series. It is awesome ♥️♥️♥️. The best lecture series I have ever seen. This semester we have complex analysis lectures and I want to know whether you have done complex analysis videos. After watching your lecture series I want to learn every lessons from you😐. If you did complex analysis videos series and other lectures after calculus 3, I humble you to upload them 😐😐😐. Thank you so much @professor Leonard ❤️❤️❤️

[@madebyyuzz]

thank you so much!! biggest fan right here

[@guidofeliz8384]

DYING TO SEE LINEAR ALGEBRA. YOU ARE FAMILY. I WILL SUPPORT YOUR CHANNEL. CURRENTLY ON FURLOUGH WITHOUT PAY.

[@ankursinha8171]

Hi Leonard, Your videos were very helpful for understanding Machine Learning especially Statistics and Calculus. IS IT POSSIBLE FOR YOU TO MAKE A SERIES FOCUSSED ON ALL THE CONCEPTS OF LINEAR ALGEBRA and CALCULUS REQUIRED FOR MACHINE LEARNING? If not now, in near future?

[@mdzahidulhasan]

One of the best Math Teacher

[@mohd_ramzan]

Thank you for everything sir. You gotta start working on new topics soon. I am getting there real fast.

[@TemplarX2001]

Thank God for people like this :D

[@duygu08123]

Passed all math courses but still gonna watch the legend

[@mwsedits]

Nice me also

[@mwsedits]

Genius

[@kuldeeppal7229]

Wait, am I studying mathematics from Henry Cavill (Superman)

[@donnie7125]

By what date do you believe you'll be able to have all of pre-calculus done by? Can you recommend any other resources for learning precal as it might take longer for you to finish the series. I'd really like to get to your calculus lectures soon! But I desperately need the foundation in pre-cal

[@chickenwithheavymakeup707]

Just start Cal 1. If you run into any gaps, Paul's Online Math Notes is great.

[@Squash101]

2x speed you can finish this within a week fam

[@NovaWarrior77]

You rule professor Leonard!

[@nvrsubhan]

hey teach, love the fire content, but imma need this series to hurry up and finish. i got precal startin in like a week, soooooo

[@1Vice876]

The 🐐 is back

[@christopherrosson2400]

Professor Leonard, I'm finishing up your calc 3 course very soon and youve basically been helping me get A grades since precal. If you could do me a huge favor and post a video on Feynman's technique by differentiating under the integral sign it would be amazing of you? You rock.

[@rashedsayem]

You are my hero 😊

[@klairehoang667]

So I have James Bond to teach me maths now, thank you the Internet

[@baljeetkour3311]

Thanks professor u r the best

[@mekusha-graphics-mekushat6493]

you are special you know how students think

[@Squash101]

Whole thing clicked for me at 26:00 lmaooo

[@paulguevara2883]

I have a question will watching all your calculus videos help me understand calculus for business calculus or would it waste my time and thank you you helped me pass statistics I watched all your stat videos

[@shaikhster4937]

Professor Leonard when will the rest of the stats videos be released? Thanks so much!

[@zeeshan7372]

U r gem sir

[@satyamverma101]

Hey there prof! Are you fine out there? You haven't uploaded at all in the last 2 months. I hope you come back soon.

[@aliozgul3906]

Very nice. Best regards.

[@jsmith5177]

Wow using test point method instead of the sign graph of factors method or is so much easier to comprehend

[@AdnanKhan-mm6bo]

I'm here just to see you.. My Professor..!!

[@lawrenceirvine8759]

that second statement does not say2x^2-5x+3, it says 2x^2

[@SourMech]

We must have a video from Professor Leonard in ASMR. I wonder how odd that will be or potentially meme worthy.

[@syedahinazainab7629]

Professor please upload videos on Higher order differential equations.

[@nm1978]

can you teach us the solutions for all polynomials, such as ax4+bx3+cx2+dx+e=0 and many others with higher roots? thank you.

[@nancyng5568]

Hey. Crazy idea- petition for Professor Leonard to teach Discrete Mathematics?

[@yash2614]

Of course !! But if you are in a hurry, you can check him out as well, I learned precalculus from professor Leonard and discrete math from Trev😊kzbin.info/aero/PLDDGPdw7e6Ag1EIznZ-m-qXu4XX3A0cIz

[@talhajaved9303]

Are you going to make videos on linear algebra and vector analysis?

[@roblox21242]

Hi professor Leonard, could you please post Trigonometry or Geometry videos?

[@techzoneplus]

Thank You.........................

[@notyouraveragejoe9527]

Can you please do Discrete mathematics and linear algebra.

[@vinayverma2578]

U change lifes.

[@muhammadsuhaimisk8913]

can you give me explain about numerical integration with three point gaussian quadrature?

[@SethuRaman-s1d]

Its just like finding domains with the condition

[@armanunited8120]

Please make more differential equation videos. There are not a lot of them.

[@abhishekthorat3631]

Professor are you going to make videos on higher order differential equations, Laplace transform, Fourier transform etc.

[@simplemathandfun4613]

Perfect

[@somasahu1234]

Wavy curve method ‽

[@0s0sXD]

Mr Leonard the audio quality is sub optimal I think it would really increase the quality of your videos if you invested in a lap microphone

[@PhakamileNdlovu-h8x]

❤❤Your amazing

[@vinayverma2578]

Yes I know superman. Yes I know prof. Leonard...

[@centozo]

Hey Leonard. I want to make a donation to you but I'd prefer it if it wasn't through Patreon. Do you have a SubscribeStar or PayPal or something where I can send you some money?

[@bryantpagan1011]

Professor, new sub here, if you ever have a chance to answer. Are the videos in this course coming to an end soon? Like is the course almost fully done with all it’s pertaining topics? I’m asking for the reason that I’m going to take calculus starting in august and will be using your videos to refresh my skill sets since I’ve been out of college for a 2 year period. I’m looking forward for your answer, if it helps I’m considering my patreon membership to start with you. Thanks in advance!
