I literally sit in math class for 90 minutes confused every second. I go to TH-cam, search up what I need to understand, and know exactly what to do in 10 or less minutes. Thank you for your help..
GUYS: (for the table of values) The zeroes (x-intercepts) are when Y = 0, not when X = 0 SO for example in the eqn. y= 1/2 (x+4) (x-6) you make an x y table of values from -4 to 6, plugging in those values into the eqn. for X Then, the y-intercept is revealed as well (0,-12) and the zeros are (-4,0) (6,0) Another way to do it without subbing in the -4 to 6 values: sub in x = 0 y = 1/2 (0+4) (0-6) y= -12 and y=0 1/2 (x+4) (x-6) x = -4 or x = 6
very helpful! But I think you overcomplicated finding the zeros. You just have to look in the brackets (x-s)(x-t) and the intercepts will be (s,0) and (t,0) but with opposite symbols
I wish that you were my teacher. Because my teacher just shows us power points about math and she only talks to the smart people that have good grades and no the people with worst grade in the class and I'm like gg I'm going to fail math

Who I was! Uncertainty enveloping my mind Till I can't break free and Maybe it's a dream, maybe nothing else is real But it wouldn't mean a thing if I told you how I feel So I'm tired of all the pain, all the misery inside And I wish I could live feeling nothing but the night You could tell me what to say, you could tell me where to go But I doubt that I would care, and my heart would never know If I make another move, there'll be no more turning back Because everything would change, and it all would fade to black Will tomorrow ever come?

Can I take another step?

I've forgotten how to see I've forgotten if I can If I opened up my eyes, there'd be no more going back 'Cause I'd throw it all away, and it all would fade to black
I teach this by showing students that a parabola is a curve where two straight lines are multiplied together. Hence what is shown as (1/2) *( x--6)(x-+2) = y y1= (x-6) is one straight line and (x+2) =y2 is another straight line and the zeros are clearly seen. Multiplying these shifted straight lines will give the full range of the parabola note that + * + = + and -- * -- = + hence both horns of the parabola extend up and out. other higher orders can be looked upon as y= (x -a)(x-b)(x-c)(x-d)(x-e) and the products of these straight lines can give the cubic etc orders . Plotting straight lines and multiplying them is a good way of looking after " quadratics "
At 4:18 you say that the x value for the vertex needs to be two away from each x intercept point, which should be four since theres a gap of eight between minus two and six ;-)
idk if this helps but in the equation y=a(x-p)(x-q) the p and q are the two x intercepts so in others words if its x-2 then the intercept is 2. then you find the midpoint of the two x intercepts to find the x coordinate of the vertex and then you plug the answer of the midpoint back into orginal equation in first sentence above to find y value
it was that simple...? boi my teachers actually good this year, i guess i got too distracted since i was pretty upset of my test grade bc i missed a day where we learned a lot messing up my test score
I dislike mathmaticians that introduce useless concepts so we highschoollers have to suffer learning these "algebra" that will have no effect in anyones life. :/
algebra is used in most forms of maths, even the division symbol involves algebra where the dots represent the numerator and denominator of a fraction. its also a bit much to say that algebra will have NO effect in ANYONEs life, it's easy to say that it's already affected my career choice. "we highschoollers" have two main subjects that will get us the furthest with careers: English for communication in general, and maths for most careers. For example my mum is currently studying psychology in Uni and a large part of it is graphing. you're allowed to dislike it but speak for yourself

facts
Exactly. My teacher gets mad when you ask for help...
@@notmarcus17 yeah i know!
@@Farah_Amjad_03thank god for khan academy!
Math really should be a student paced class
Less than 5 seconds into the video
My brain: aight imma head out
that's exactly me when i read ur comment
god bless youtube 💀 speedrunning the course two hours before the test 😅 thank you so much, for these!!
GUYS: (for the table of values)
The zeroes (x-intercepts) are when Y = 0, not when X = 0
SO for example in the eqn. y= 1/2 (x+4) (x-6) you make an x y table of values from -4 to 6, plugging in those values into the eqn. for X
Then, the y-intercept is revealed as well (0,-12) and the zeros are (-4,0) (6,0)
Another way to do it without subbing in the -4 to 6 values:
sub in x = 0
y = 1/2 (0+4) (0-6)
y= -12
and y=0
1/2 (x+4) (x-6)
x = -4 or x = 6

Yeah same here, buddy.
Nowadays mostly teachers are like that
me speedrunning math exam the day before the test 💀
what happened to the 1/2
u divide the 1/2 by -16 which is -8
Thank you! This was very helpful!
I still don’t get this
😤
Did you watch the previous video. This is more of a follow up
u always have a video for what i want but i never can keep up with what ur saying, u make it sound much more difficult than others creators
Theres a special place in heaven for these people and this channel
This was such a banger. Love supporting small channels ❤❤❤

You could tell me what to say, you could tell me where to go
But I doubt that I would care, and my heart would never know
If I make another move, there'll be no more turning back
Because everything would change, and it all would fade to black

I've forgotten how to tell, did I ever even know?

Was here before thumbnail loaded in. I already know the vid os gonna be great. Thanks.
towards the end when you plug in the number for x to solve for y, shouldn't we be plugging in -2 not positive 2?
i know this is 11 months old but hes plugging in the 2 that is in between the -2 and the 6 because that's the one that's the x axis for the parabola.
@@morningstar.. omg thank you I didn't understand why he put 2 lol.
At 4:18 you say that the x value for the vertex needs to be two away from each x intercept point, which should be four since theres a gap of eight between minus two and six ;-)
Really nice explanation.
this taught me better than my math teacher ever could
Nice video buddy! This really helped me save my math mark. Thanks
very helpful,thank you
Thank you so much!
It was easy and fun learning with u....
common sense went out the door
Do u show compress or stretch on graph in factored form?
Im still not sure how u guys understand this
idk if this helps but in the equation y=a(x-p)(x-q) the p and q are the two x intercepts so in others words if its x-2 then the intercept is 2. then you find the midpoint of the two x intercepts to find the x coordinate of the vertex and then you plug the answer of the midpoint back into orginal equation in first sentence above to find y value
haha lol whatever helps i guess
No i feel u, i can get like that, where u just want to stop caring
what program are you using?
Thanks so much man
it was that simple...? boi my teachers actually good this year, i guess i got too distracted since i was pretty upset of my test grade bc i missed a day where we learned a lot messing up my test score
Thanks!
I have a final tomorow
How'd you do?
How did you do on it?
how was it bro
is 1/2 in this equation a?
Didn’t put ^ on the end of the porabola you can get marks off for that
Sorry where do you put it on the parabola
@@hoyboy6150 late but at the ends
@@AHoomanb Oh right like the arrows to say that it continues, yeah I hate that
How can I find other points to graph?
acaba nasıl 1 hafta boyunca anlamadığım konuyu 5 dakikada anladım bilmiyorum
Khan I love you so mych
This is SO COOL
Thank u so much! big help
LETS GOOOOOO
how do you find the 1/2 from the graph?
umm...i am 13 years old and i still don't understand a single word
HElp..
Why do you equate the expression with 0
You have to find the x intercepts for both points

I sure wish I hadn't thought algebra was useless in high school as I am studying to be an engineer now and have to retake it, pay attention in class
Lol
Yoo tryna give me your yt acc?
Coazed why would I give you my yt account?
love u sal
g'day fellas
Do u show compress or stretch on graph in factored form?
