Three Forms of Quadratic Equations

We will quickly review three forms of the equation of a parabola. These are the standard form (which quickly tells you the y-intercept), the vertex form (which gives you the vertex [h,k] ), and the factored form, which tells you the roots, or zeros, of parabolic functions. We'll do a worked example to convert between the three forms of parabolic equations. We'll complete the square to find the vertex form, and find features of the graph of a parabola, including its axis of symmetry, vertex, y-intercept, minimum value, domain, range, and complex roots.

Yes this deepen my understanding on quadratics.. Thanks!!

Helped alot! also the determination of solutions can be done through discriminant, b^2-4ac

Seems like a good video except I would not recommend this for beginners at all because I thought this was supposed to an introduction and I did not understand anything that was said in the video. I think explaining it in a simple way from the basics would be more helpful for people who have never done the three different forms before.

thank you so much this helped me a bunch to understand quadratics!!!!

I wasn't understanding anything until you showed us (-b/2a), then everything made sense XD thank you!

Can someone explain to me the uses of imaginary roots?
