hi why are some inequalities written separately but some are written as one whole inequality such as at 5:48 (the first 2 questions) also thanks so much for the video
dont know if i need this till but im guessing its becuase the region your are writing about is connected when its less than < and seperated when its greateer than>
I think its because if you write it together, it wouldn't make sense as it would say that x is smaller or equal to -3 and that x is bigger or equal to 4, which would not make any sense if put together. So its better to keep it separate :)
I think yes, because if you write it together, it wouldn't make sense as it would say that x is smaller than -4 and that x is also bigger than -1, which would not make any sense if put together. So its better to keep it separate :)
ok so basically if you look at graph the graph extends beyond -2 and 6 (if the question has > and equal it means that you look at where the line is above he graph and if it is < and equal you look at below graph) therefore no values that are between -2 and 6 so therefore the values must be all values less than and equal to -2 and all values greater and equal to 6
Sir, I'm sort of confused with these questions. Why don't shade above and below all of it when representing the certain regions of the graph? The '>' sign always has two end parts shaded above and not the middle. The '
If it's less than 0, then it would be under the curve because 0 is the x axis. If it's more than 0, then it would be above the curve. There are different ways of writing this, like: (value)
If it's in an n-shape, the inequality will have a negative x squared term. Multiply the whole inequality by - 1 and solve like he did in this video. It will still work. Don't forget to switch the direction of the inequality when you multiply by - 1
No, they're not always equal to zero. But we can manipulate them to equal zero. We have methods to solve quadratic equations WHEN they are equal to zero, so it's important to get them equal to zero.
BrO, it is the night before my maths GCSE and you made me to the biggest OOOOOOOOOHHHHHHHHHH NOW I get it, @emjays9543 yes Below ground Zero properly helped me understand.
i didnt understand this till i watcged this video thanks.
Love your phrase 'below Ground Zero'. That will help me remember how to solve these.
Thank You
threr was an explposion below ground zero on 9/11 an inside job of course
Tysm, I was struggling, I am glad I found this video!
Thanks for making these videos they really help!
I've got a math exam in 2 days and this has helped me a lot
Did you pass it?
I got an exam in 3 days haha.
Thank you so much- this is very helpful, God Bless truly xx
You saved my addmaths exam ly x
Thank you so much I was struggling even tho my teacher explained it for like many times
This really helped me
Wow. Mind blown🤯.... Thank u easy to understand and colors helps 😊. Just subscribed 👍🤗❤️
This is so good thx !!!
Great video, I love how you explained it, I love you. xx
my good sir, you are a life saver
Brilliant explanation, thank you

thankyou for solving a very big doubt i had
Is it significant that it's written as x < -4, x >- 1 rather than -1 < x < -4
yes
Shushhhhhhhhhhhhhhhhh
Ive got the same question @mathsgenie

Question, 3:31 why is it less than -2 but bigger than 6?
ok so basically if you look at graph the graph extends beyond -2 and 6 (if the question has > and equal it means that you look at where the line is above he graph and if it is < and equal you look at below graph) therefore no values that are between -2 and 6 so therefore the values must be all values less than and equal to -2 and all values greater and equal to 6
So helpful
yes please use light ode next time
its easier and nicer to learn when the background isnt dark
what if the zero is not a zero and is say, for example, a 6?
you jus make it 0

Maths Genie I'm confused on where you getting the less than or equal signs!
If it's less than 0, then it would be under the curve because 0 is the x axis.
If it's more than 0, then it would be above the curve.
There are different ways of writing this, like: (value)
Ya'll better wish me luck
Good luck

so what has your fate become
All the quadratics videos assume too much knowledge. I need an intro.
True
Excellent thanks
Thanks
Thanks for the video..!
But I have a doubt, how will I understand that the graph will be in u-shape or in n-shape?
If it's in an n-shape, the inequality will have a negative x squared term. Multiply the whole inequality by - 1 and solve like he did in this video. It will still work. Don't forget to switch the direction of the inequality when you multiply by - 1
@@jedmaths1152 Thanks a lot!
calculate y?
Do quadratic equations always equal to zero
No, they're not always equal to zero. But we can manipulate them to equal zero. We have methods to solve quadratic equations WHEN they are equal to zero, so it's important to get them equal to zero.
JED Maths thnx
Thank you so much
Legend.
dope, thanks
Finally got it!
thanks sir
WHY DID YOU GO FROM +3 TO -3 AT 4:27???????????????????????????????????
Aurora xo we are looking to make each bracket equal to 0. If the bracket is (x+3) then x=-3.
yes nigga
