Learn how to write the equation of a parabola given vertex and a point on the graph

The video tutorial explains how to write equations in vertex and standard form. It begins by introducing the concept of vertex form and its usefulness when given a vertex. The instructor demonstrates solving for 'a' in vertex form using given points and emphasizes the importance of parentheses in calculations. The tutorial then covers simplifying the equation using order of operations and converting the equation from vertex form to standard form, highlighting the use of the distributive property.

Why is it important to use parentheses when simplifying equations?

What are the values of H and K in the vertex form equation, and what do they represent?
