What is vertex form of a parabola EQ

The video tutorial introduces different forms of quadratic equations, focusing on the standard and vertex forms. It explains the standard form as y = aX^2 + BX + C, where A, B, and C are real numbers, and A cannot be zero. The tutorial then introduces the vertex form, y = a(X - H)^2 + K, highlighting the differences in variables and components between the two forms. The video emphasizes the importance of understanding both forms for solving and graphing quadratic equations.

Why is it important to learn different forms of quadratic equations?

How does the value of 'a' in both standard form and vertex form affect the graph of a quadratic equation?
