Learn how to identify the vertex and axis of symmetry using completing the square

The video tutorial explains how to group quadratic and linear terms, factor them, and complete the square. It emphasizes the importance of handling fractions without converting them to decimals. The tutorial also covers the difference between factored and expanded forms and provides a graphical analysis of the function. The teacher concludes with a discussion on the vertex, axis of symmetry, and horizontal compression, encouraging students to use a graphic calculator for verification.
