Learn how to complete the square and identify the vertex, domain and range

The video tutorial covers the process of factoring quadratic expressions and completing the square. It begins with grouping terms and factoring out constants, followed by completing the square to transform the expression into vertex form. The instructor explains the importance of maintaining equivalent equations by adding and subtracting the same values. The video also discusses finding the vertex, axis of symmetry, domain, and range of the quadratic function, emphasizing the impact of negative coefficients on the graph's direction.
