[peacy]

Thanks making these videos, they're all so clear and helpful!

[slemz]

this really helps me as a student that moved to higher last second.

[OmniversalInsect]

Thank you, this is so helpful when your school sets homework in lockdown without even explaining it

Visualisation at start was a great idea!
Putting these 3 equations (e.g. x^2+y^2=17 and y=x-3 and x^2-3x-4) into an online graphing calculator really helped me visualise what's going on. You have the circle, straight-line and/parabola all one graph to confirm coordinates. Good fun!

Hello sir, I just wanted to ask if I could use the quadratic formula at the last stage instead of factorising. Thank you

[Dentipreneur]

Thank you very much for all of your videos, they help a lot.

Hi
I think you got the values for y wrong as you rounded instead of using the full number
Y should of equaled to 3.89 and -5.09 instead of 3.88 and -5.08

[lawesyb]

thank you! I finally understand how to do this now :)

[subdZerox]

for the last question i got y = 3.89 and y = -5.09, did i go wrong or would i still get the mark. Thank you tho the video was great

[lilia_casburn]

These videos are actually really fun to do 😊 makes the questions appear so simple, thanks!

[zainthe_clkid]

My teacher was horrible doing this, now that you have helped me, I can actually get 5 marks on a question!! Thanks!!!
