Many teachers focus on the method only and many like to focus on the logic also , although the video is 11 years old, the only one I found which gave a little of reasoning why we can equate both the equations. Well done

[@SadiqahRH]

I absolutely love your site- don't know where I'd be without them!

[@ExamSolutions_Maths]

Thank you. All the best

[@hedonism13]

Thanks - really helpful!

[@ExamSolutions_Maths]

@hedonism13 Pleased to hear that - thanks

@Wii624 Just check out my video on using the quadratic formula. It must be something in that you are doing wrong.

[@DJMorris97]

Just a quick clarification, I could do this with the equation of a circle instead of an equation of a parabola when required to find the point where a line and circle intersect? Can't see why not but just checking.

[@user-of6rp5ww4d]

Love it

[@timothya.g.991]

Thanks!

[@ExamSolutions_Maths]

you're welcome timothy!

[@Rydexify]

Have you done a video on parabolas before this one? I can't find one from your website

[@Drkhan345]

was stuck on this so hard our teacher was off and i had attempt to self teach myself this found it too hard but wow came across this and never found anything so simple and helpful much love!!

[@ExamSolutions_Maths]

You're welcome

[@Wii624]

Thank you so much. Would you be able to post a video of what to do if you can't factor it??? I know we have to do the quad formula but I can never quite get the right answer. Thank you!!

[@piptip694]

Quadratic equation can be solved in there ways 1) Factorise( Proceed with middle term breakdonw), complete the square r using yt videos

[@themediumcheese7484]

What if we didn't have equations that automatically had the y-value in terms of x?

[@c9wind]

rly helpful thx

[@ExamSolutions_Maths]

No problem, best wishes.

[@gamefuler]

what if the terms aren't factor-able? Using the quadratic formula doesn't yield the same results of the answer spread either

[@ExamSolutions_Maths]

+gamefuler Use the quad formula. You must have tripped up in your working as it should lead to the same result if you use the formula.

[@mathsunmasked56]

Well done! I'm making videos for my students too. Can you tell me what drawing software you are using? I've tried several but don't recognise this one.

[@omardastgir2985]

2:30 could you just use simultaneous equations instead?

[@tanim.3578]

chill with the ads tho sir

[@more0716and2]

what if the equation of a curve is x^2=4x-y^2? How do I change it into the form of y=ax^2+bx+c?

[@ExamSolutions_Maths]

You can't

[@TheOwnerPO]

hi, how are you ?

[@karlborg7938]

Xeasy lalla

[@everywhere7653]

Omg can u explain because u are just doing it

[@KnucklesPlaysMC]

every where I understand it

[@betul-ev2fu]

he is explaining wdym

[@Rydexify]

Not bad u?
