it actually can if you ask for the specific X and Y

Bro you are actually so underrated thank you so much

My pleasure mate 🙏🏼 Blow up coming this year hopefully 🚀

-b/2a = x value of turning point = -(10)/2(1) = -5 Plug -5 back into the quadratic to find y value f(-5) = (-5)^2+10(-5)+24 = -1 Turning Point = (-5,-1)

Bro you're smart.

Amazing 🥰 I'll understand, answer and pass my exams with flying colours in the same way Amen🙏

You just earned a new subscriber❤

Thanks so much, first day of geometry and reviewed from last year. Didn’t get any of it and now I do in 2 mins of trying thx so much.

Great to hear! So glad it helped 🤩

thank you

Another way is using -b/2a = x or just turning the equation into the standard form and solving it

Do -b/2a and plug the answer into the quadratic to get your y value and use the same x value

OMG GOD BLESS YOU OMGGGG I WASN'T UNDERSTANDING ANYTHING YOU SAVED ME THANK YOU THANK YOU 🩷🩷🩷🩷

I love you

Bro thanks.. here is an easy way of doing it a=1 b=10 c=24 Step 1. p= -b/2a p=-(10)/2(a) p=-10/2 p=-5 Note: p is equals to the x coordinate . Step 2: q= 4(a) (c) - (b)²/ 4(a) q=4(1) (24) - (10)²/ 4(1) q= 96 - 100/ 4 q=-4/4 q= -1 (-5,-1) Note: q is equals to the y coordinate.

Thank you for the helpful video

never have i understood math so quickly, thank yo broski 🫶

If the x was a number would u also divide the number by 2? Pls someone tell me I have my maths test tomorrow

thanks for saving time\

Why do you subtract 25

🥰🥰🥰 the tutor😅

Wow

Why does he half x^2 and 10x? Just a step that confuses me a bit🙏🏼

Too much stuff I gotta learn might as well just flip burgers but cheers mate

❤❤❤

when we have a quadratic eqn with a negative coefficeint, does this still work as is or must we take the - sign in common and THEN carry the formula out?

❤

wait but how do you plot the graph

Isnt dy/dx easier… (help im going insane over this.. quadratic graph😭)

@mygcsemaths

6 ай бұрын

You could also find dy/dx, set it equal to zero, solve for x, and sub in to find y

what if the coefficient is an odd no. ?

@Mathspaperks1ks2

Same idea you would halve the odd number so you would just half it.

hi what to do if there are two turning points will this trick work in that

No it won’t, but you don’t have to worry about any graphs with two turning points in GCSE Maths

A quadratic only has one turning point but for equations with two turning points you can use calculus. If the derivative = 0 and the second derivative does not = 0 then it is a turning point. If you find all the x values that make the first derivative 0, you can test them by plugging in to the second derivative to make sure the second derivative does not = 0. You can then plug in all the x values that passed the test into the original function to get the y coordinates of the turning points. I also think it is easier to use derivatives for quadratic functions to find turning points. You can super easily find the derivative in your head which would be 2x + 10. If you set it equal to 0, you get that the x coordinate is -5 and you plug that back in to the original function to get the y coordinate. You don't need to check the second derivative because there are no points of inflection on a quadratic.

Diffrentiate and equate the function to zero ez

Why did the (x+5)² become -25?

@mail9897

10 ай бұрын

When you change x² + 10x into (x + 5)², the x² and the 10x remain the same, but you end up with an additional product of 25, which must be negated by subtracting 25.

basically what he did was +(5)^2 which went in the bracket with x making it (x+5)^2 then -(5)^2 which gave us -25. If u want to know the reason behind this, he used the completing square method. I recommend watching a few videos on it as it is really easy to learn and helps a lot with problems like these and is the easiest method to figuring out equations of circles.

Here is something for you a=1 b=10 c=24 Step 1. p= -b/2a p=-(10)/2(a) p=-10/2 p=-5 Note: p is equals to the x coordinate . Step 2: q= 4(a) (c) - (b)²/ 4(a) q=4(1) (24) - (10)²/ 4(1) q= 96 - 100/ 4 q=-4/4 q= -1 (-5,-1) Note: q is equals to the y coordinate.
