Took the teacher the whole class period to try and teach me this. I literally picked up most of it from just 2 minutes of your video. I appreciate your work man, thank you!

Speedrunning my whole semester. Final in 7 hours

I could never get past algebra in school. Now I'm 60yrs old teaching this to a foreign teenager ~ you make this so simple to teach!!!! Thank you very much!

[elizabethhall]

PSAT tomorrow😃

You make it so easy! I had no clue what these were when I started the video. I paused when you introduced the second one, solved it, and got it right! Thank you🤩

Why did this help me more than my teacher

[johngravesyt]

You explained in 5 minutes what my algebra teacher couldnt explain in 45

[cannonvigue]

Took my class 10 days on this entire unit, yet you can teach it to me in under 6 minutes, very impressive.

I'm not even in school anymore. I'm 25 years old and this is still haunting me and kicking my ass.

[samanthagalacio]

Thank you so much for this, dear teacher. You literally saved my brain.

[maryamhazim]

I'll watch this video 20 times, say it's easy, try to do it on my own and barley remember anything

[Kevin-riwf]

damn I was supposed to learn this in class but corona cut us short so now I'm in high school getting tested on shit I haven't even learned

[Michael-iewk]

I’ve never attended this lesson because I hated the lecturer and this was so helpful ❤

[gingerbread]

I've been struggling for well over a week with this, and instantly got it in 3 minutes. THANK YOU!!

[trinityhamilton]

you've explained in less then 6 minutes whats taken my teacher to try and explain in 7 weeks.. thank you so much!!

[Cosxmix]

i legit understood this in the first 5 mins
compared to when i sit in class for 1 hour

[crystaldavis]

I really wish these teachers explained things like this...

[jamesrobinson]

Had about 3 classes on this, did a test on it, failed the test. Got extra maths tutoring to help me, the maths tutor gave me this for homework. After multiple classes in school, multiple classes with a private tutor, I still couldn’t understand but this video made me understand in the first 2 minutes.

[Quaplex]

This helped me more than all the other quadratic formula videos as a 3rd grader.
Mainly because it gives more detail.
Thanks for the help!

You're a lifesaver!! I can finally catch up on 16 freaking missing assignments in algebra2A because you helped me get rid of this roadblock. I am absolutely coming back should I need help. You're fantastic!!

Update: I ended up having 73 missing assignments in all four of my classes combined and I got them all done in 17 hours :D
