Solving nonlinear simultaneous equations

Here we look at some examples of solving simultaneous equations where one equation is nonlinear. We attack this problem by using a substitution method.

I can already tell that I am going to be referring to your videos a lot since I am in advanced math year 11. Thanks for this

The solution for the last one is in imaginary numbers, if I'm not wrong. For your A*-U spec or 9-1 spec you won't be asked that. Additionally, it'd be a good idea to learn how to complete the square as they do specifically ask that sometimes. Hope this info helps you, wherever you're reading from, good luck on your path <3

shouldn't you get -30 when you initially move it to the other side of the equal sign?

Ayy this was super helpful! Thanks a million! :D

[laurenwatkinson]

so if i had y=x^2
y=2x -1
it would equal
(x, y) = (1, 1) ?

[WethuMagagula-qofl]

Sorry why don't we write the x-squared as a negative since the sign before it was a
Minus when making the quadratic to be on one side

holy shit, thank you. we're doing this for year 11 advanced maths, and damn this can become confusing. lifesaver!

[kweenc]

this is a very helpful video. thank you!!

not all heores wear capes, thank you so much this video helped me, i have an exam in like 2 weeks and i zoned out during most of my classes lol. again thx!

[hhhhhhhhhhhhhnhhhhhhh]

Thank you, the one day I was off we did this and then we've done nothing but them with no input from the teacher, just worksheets for three lessons so that's fun

[kyleclement]

if positive 30 goes across the equal sign its supposed to be negative

[rishabmanga]

sir you made a mistake, you were supposed to take -30 when you moved 30 to the left hand side in the 2nd example

[bourgeoisbenny]

i dont understand why does x= 4/5 ????

[zepityt]

I swear this is the video I watch during A Maths

[maxzjk]

I forgot to revise this topic and lost 5 marks on the exam🙂💔it would be too easy if I REVISED

[paulmangena]

you made a mistake on the last one bro whenn 30 moves to the left it becomes negative

[wafIeee]

hi im grade 2 thank you so much for this it really helped
