Understanding Standard Form, Factored Form, and Vertex Form of a Quadratic Equation

Three forms of a quadratic equation are introduced in this quick video. For an organized list of my math videos, please go to this website: sites.google.com/view/nabifro...

W man

Printed out some worksheets. Are the answers available?

[@Nabifroese]

If you got worksheets from my website I think most of them have answers at the bottom of each worksheet. Let me know which one does not and I will have a look. Thanks!

i love when x’s aren’t the fucking x’s in the equation

Your explanation of finding the middle was horrible, why do you divide by two? Care to explain?

[@Nabifroese]

You are right! This video is supposed to be an overview of the 3 forms... but I couldn't help myself and started talking about how to go from factored form to vertex form. That is content for another video! My apologies! As for an explanation... if you know the two x-intercepts (or zeros) and you find the number in the middle of those two x-intercepts, you have found the x-coordinate of the vertex. But again, this isn't supposed to be the focus of this video. Us math teachers sometimes get off topic, and I apologize!

@@Nabifroese Thanks! Not my comment, but it does clear some stuff up.
