Thank you so much, This really helped me!!! Ive been behind on my math and I just couldnt get passed this lesson but with this video it just explained it all

That moment when you learn more in a 6 minute video than in a 2 hour math lesson

Man now I know it's not about the time but about the teacher 2 hour math class nothing learned but a 6 minute video helped me out thank you!

Awesome! Can you also do a video on how to find the axis of symmetry if you are given the graphed parabola only?

[boo_kwanon]

what if the equation is x= y²+by-c? what would be the formula for it?

[johnnoemartinez]

what if your b is equal to zero? the given is y = x^2 - 25

[clownkid]

would anyone know what A would be if the equation just gave you x^2?

Isn't equation of parabola...y²=4ax
