Rewriting Quadratics in Standard Form to Reveal the Vertex

This video tutorial teaches how to rewrite quadratic functions from standard form to vertex form by completing the square. It explains the importance of different forms, how to identify the vertex, and addresses common misunderstandings in the process. The tutorial includes practical examples to reinforce learning and ensure understanding of equivalent functions.

Describe how to ensure that the value of the function remains unchanged when completing the square.

What common misunderstanding might occur when adding a quantity to a function while completing the square?
