Finding Turning Points using Completing the Square

[@emmatamago]

I'm only about a minute into the video and I've now learnt more about turning points than in several 50-minute maths lessons. Thank you!

Surprisingly easy to find the turning point from just a and b. Many thanks!

Thank you so much, I’m a year 11 student and I have struggled so much with quadratics. This video is now going to be my go to for revision. Thank you!

[@rebeccajohn8672]

You're so good at teaching, my math teacher doesn't do ANYTHING useful so I'm always left clueless at the end of each class. I have a math mock exam tomorrow and omg this video helped me SO MUCH! I might not totally fail thanks to you! ^.^ Thank you!

Is it just me or does this guy sound like the mygcsescience physics guy? Great video though.

[@corbettmaths]

I watched one of the videos there and I'm sure he is a great guy but personally I don't think I do 🙊😜

[@pain9594]

when you don't pay attention in online classes, panic, and then remember that gifts from god like these exist

[@diaryofaweirdo4645]

At 5:50 ish why do you move the graph for to the right not the left? You said it become (4,-15) so why does the 4 become positive? Thanks :)

[@lourdisefmn8035]

thankyou so so much🙏

[@huiying7883]

Thankyou so much !

[@_godsl4yer_]

Can you explain why when I do (x-4)^2-15 = 0, I can't do x=4+15 assuming that (x-4) are the two factors? But instead I have to +15 on both sides and sqrt both side and then +4.

[@Kazzaofficial]

Is thus foundation?

[@corbettmaths]

No this would be Higher! 👍

[@rex1306]

Great video!!!

[@godfreykatongo3184]

Perfect

[@phantomgaming5379]

Thank u so much

[@vaibhavmaloo7909]

thank you

[@beanmachine1248]

Cheers mate

[@TheKingCreeperChanne]

Thank you :)

[@sumaya6718]

5:23 its wrong because a minus and minus makes plus so shouldn't it be positive 16 not negative

[@corbettmaths]

I'd recommend you watch my video on Completing the Square. If you expand the brackets, it is +16, that's why we put -16 afterwards, to give zero

[@moonclose9787]

Thank you
