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!

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

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.

5:23 its wrong because a minus and minus makes plus so shouldn't it be positive 16 not negative
@corbettmaths6 жыл бұрын
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
