Even in the unedited video, you seem to make very few speaking errors. You're an excellent teacher.

Remember please that positive 18 plus negative14 is equal 4 not 5. Thank you

Hey Brian
I've been struggling a LOT this year when it comes to maths, gr9 has been incredibly rough, factorization, equations, algebra the works.
I just wanted to come and say thank you for your help, your videos are super helpful and concise with how they explain. Without your videos I probably would've failed math this year, and I'm so grateful for them.
It's my last week of the year, got a few more exams to tackle, but thanks to you, I feel much more confident, and my grades and scores have improved a lot.

So thank you sir. You've earned a subscriber. ❤

I thought i was lagging when u said it twice 0:40

Great video showing some examples of the good old completing the square, I've some students so eager to drop that practice thinking it would not show up anymore, more so after learning the quadratic formula... until analytic geometry :) (Just a really minor correction, on the first equation the radius should be 2)

thanks for helping me understand and rapping like my teacher, helped me a lot!

[NovaYoutubesBadly]

This helped me a lot studying for my MATH110 final! Thank you so much!

how did you add 9 and 16 on the last problem when you subtracted from the left side of the equation? I'm so confused! I thought you need to do the same on both sides

Sir please solve the chapter 8 of this books next week is my mid term exam and i don't anything about it

[ignacioperoni]

Thanks for the help I could finally figure this out

[suryaprasad]

Just use the formulae
For general equation of a circle
X^2 +Y^2+2GX+2FY+C=0
Center is (-G, -F)
(Radius of the circle)^2 = G^2+H^2-C

Hello Sir nice video. Hmm. Sir i have also a method that can solve center of a circle and ellipse in just 5 seconds.

[onesalcenat]

Professor, why you don't add 14 in the both side?

[arxooalpha]

That’s 4 not 5 ( -14+9+9) and the square root of 4 is 2.
Right?

How did 9/4(4) became positive nine? On 15:56

[wengmagteach]

why not divide both sides of the equation no. 3 by 4 instead of factoring

[autisticanimator]

At the end you used x when you should use y

[Ian-kqem]

where tf did the 6 comes from in the second step

[Chiro-nuzm]

The radius of q1 is 2

[okikioluwapopoola]

made an error for the first question the radius total is 4 so the square root of 4 is 2
