Complete the square to find the vertex of a parabola

👉 Learn how to identify the vertex of a parabola by completing the square. A parabola is the shape of the graph of a quadratic equation. A quadratic equation can be written in the standard form (i.e. in the form y = ax^2 + bx + c) or it can be written in the vertex form (i.e. in the form y = a(x - h)^2 + k, where (h, k) is the vertex.)

Given a quadratic equation in standard form, to obtain the vertex of the equation, we use the process of completing the square to rewrite the equation in the vertex form and hence extract the vertex of the parabola formed by the equation.

Watched these videos for my first algebra classes years ago. Here I am again for precalculus. Thank you.

U saved me honestly
SUCH A GOOD EXPLANATION
deserved a sub

I owe you my life. Finally, a video that gets straight to the point! You had me at 2:35.

Yet another math test Brian has saved me on!

you are by far the best teacher I have ever seen on yt thank you

[tyro]

This makes so much more sense thank you so much

[justinle]

why did the -1 (in red) disappear at the end? i'm confused there

Great, but now I'm left to fend for myself trying to find whether the vertex is a minimum or a maximum
