We will graph the following equation y=-2x^2+4x+6 in the form of y=a(x)^2+bx+c, by finding vertex=?, y-intercept=?, and x-intercept=?

You just saved my Algebra exam, you're amazing
Glad you found our videos and we were able to help. 🙂
4:38 That smile was everything! You seem so sweet and this video was really helpful! Thank you so much!
Couldn’t remotely comprehend the question before this video!!! My main teacher has gotten sick for 2 months now and our relief teacher did not cover this topic at all, but still expects us to know what to do… Thank you so much again!!!
You are welcome. Glad you found our videos. 🙂
Mine too
THANKS A LOT!! OH MY GOD I AM SO LUCKY TO FIND U ON YT, UR VIDEOS ARE AMAZING!!
Glad you found our videos. (There are over 10,000 of them.) Thank you for liking them.
this is by far the only video that helped me understand the concept without confusion, thank you so much (:
You are welcome. Glad you found our videos. 🙂
Thank you so much, it’s my teachers last year before retirement so she doesn’t teach and just expects us to get the homework and learn from doing that
Omg!!! Thank you so much I was so confused in my algebra class cause the professor was skipping steps now everything makes sense!
You're very welcome!
Thanks heaps for making this! i missed a few classes and was way behind, this video is easy to understand and to the point, unlike my maths teacher sometimes!
Glad it helped!
this video is really amazing. It helps me with my problems. I recommend that students who self-study watch this video.
Thank you. Glad you found it helpful. 🙂
So there are 2 x intercepts how about y intercepts?
i know it’s 3 months late, but the y intercept is 6 since it crossed the 6 axis it was the second point he did on the graph (0,6)
I swear to god I understood this so fast then in class thanks so much man
Glad you found this helpful.
finally I understand in this video now its easy for me sir you make my day my language is different but I did it / respect from Turkey
🤩
Thank you . Welcome to the channel
Thank you a lot sir, I was troubled by the maximum height achieved by a rocket sum and i needed to find it by using an equation, i was able to solve it using your video.
Excellent. Glad you found our videos. 🙂
Lifesaver sir! Thanks 🤟
Glad it helped! 🙂
Thank you this vid helped lots
Glad you liked it. 🙂
This was perfect thank you
You are welcome. Glad you found it helpful. 🙂
Sir, what would have happen if its was a fractions instead? How to solve it?
Yes! Amazing job. Im taking an online precalc and it's missing that personal touch.
Glad you found our videos. We also have precalculus videos as well.
If b is negative does it change to positive or stay negative
It depends on the value of the other two constants.
Positive I’m pretty sure
Thank you so much
You're welcome
So my given was -x^2-4x-5, does that automatically mean its a0.. what could i have possibly done wrong? :(
Was it given to you in the form of an equation? y = -x^2 - 4x - 5 ? This graph opens downward. Note that - (5)^2 = - 25 and - (-5)^2 = - 25
@@MichelvanBiezen i just fixed it, i accidentally made the -4 a positive 4 while solving for h 😅😅 now its opening is downwards, thanks so much for replying 😁
Very helpful thank you
Glad it was helpful!
hi there,can we apply quadralic formula for y=0 and just do delta?
What if you cant factor it
Then you have to use one of the many other mathods to find the roots. (shown in other videos on this channel)
You are a lifesaver , W person
Thank you. Glad you found our videos. 🙂
I LOVE YOU SO MUCH
Thank you. Glad you found our videos. 🙂
Thank you soooooo much! I was stuck on a question exactly like this. I was afraid my mom would get mad because I was doing my assignment in the last moment. This video made me understand my work and now I can do it in just a few second. You just saved me.
Glad you found our videos. Next time don't wait till the last minute (that is what I do and it doesn't work well). 🙂
@@MichelvanBiezen sure thing I’ll remember that for next time thanks for the advice! 😄
Thank you so much! ☺️
You are so welcome!
How is -(4) became positive?
If you are referring to the first line. we have -4 / (2)(-2) = -4 / -4 = 4/4 = 1
son of a gun I thought the a Value had to be positive, so I divided the whole equation by -1. Got the same numbers for vortex, just wrong signs. (I only watched as far as figuring the vortex.)
edit I fully watched, and yeah the step I took that messed me up I would only take if completing the square to solve for the x values. Cool video and love the bow tie. (reminds me of my dad he always wore one and was a great man)
Glad you figured it out.
tysm
2•-2 is -4!
The negative cancels out with the negative in the numerator.
Nahh my boi u saved my ass thanks
Glad you found our videos and you found them useful. 🙂
ILYSMM
Thank you. Glad you like our videos.
,👌👌👌👌
blud wheres the x-intercept?
The y-intercept is 6 (when x = 0) as shown in the video.
Blud
I don’t think he gets the point
