Simultaneous Equations with Quadratics

How to solve simultaneous equations involving quadratic and linear equations.
And can you spot how I could have solved the first problem much easier? I think I missed a simpler way...

This topic is baffling, I literally lost my brain cells to this, oh god.

thank you so much- i was stuck on this for ages, it's such a coincidence that the first part was the exact equation i was doing in my textbook, so glad i found this video!!!

Hi can you please go through vector questions that involve ratios and fractions, the harder ones exam questions. I have pictures of a few

[blackoutemzz]

Do hard problem solving. Thats the only thing i need help on. Thank you if you reply

This video was really helpful. Thank you so much !!!!

Sir as the grade boundaries were 124 for a 7 last year how many marks do you think it will go up this year thanks in advance!!

[angelafinlay]

Thank you so much. This topic was explained clearly and very helpful.

[tonyzambonistarkoni]

are there any videos on this channel where they cover simultaneous equations with 3 unknowns? if not, please go through them

Sir what was that website that would help you with maths strategies made by some maths teacher?

Hi, thanks for this video it was really helpful. If you haven't uploaded one already, is it possible if you could do a video on congruent triangles.

6.55 how do you know that is x? how to find x? can you explain again?

[haroldking]

Hey if possible could you go though some hard ratio questions please, I always seem to struggle on them. Thanks.

[ishanpatel]

Thanks bro you helped me out in a real tough spot, much love :D

[yxng_shiv]

Great video, wish my teachers could teach like you.

[tyknox]

Thank you very much, quick, simple and I love your voice haha

What will happen if both are quadratic equations? will it make any difference to this method explained in the video?

[liable]

why cant the equation at 9:35 be factorized why do we have to use quadratic formula?

[Max-mnqn]

2:59 Why does x equate to either of those values?

[ipodzonly]

If we make x the subject, do we just substitute that into x in the second equation?

For the 1st question could you sub y into equation 1 immediately
