The background music is inspiring! And I like the zoom in action which makes the steps more clear. Recall step is good for understanding. Also different colors makes viewers more convenient to learn. I can tell the movie make put great effort on the editing of this movie. In all, this is a video I would like to recommend to whom want to learn how to find the vertex of a quadratic equation.

I like the way Mr. Ramirez has all of the equation to find x present and also the equation of the quadratic formula. It makes it easier to follow and understand what a,b, and c values. One thing I would like to see is maybe a clear and concise definition on what a Vertex is.

I like how Mr. Ramirez clearly compares the standard equation with the equation we are using to solve and shows what the a, b, and c values are. I really like how clear he makes the negatives (sticking the negative sign of -b/2a out in front to differentiate from the b in the problem being negative). The color coding was extremely easy to follow. I like that he reminded us the solution at the end was the equation's vertex.

Mr. Ramirez does a good job making this video easy to follow. He uses colors and goes through every step very clearly. I also like how he explained what the general form of the quadratic equation is, as well as the general form of the x-coordinate of the vertex. This is helpful in applying the concept.
