This math topic focuses on converting quadratic equations from standard form to vertex form by completing the square, specifically when the leading coefficient is -1. Practice is provided on identifying the vertex of the parabola represented by each equation. The skill of manipulating quadratic equations and finding the vertex in context is developed across multiple exercises. Each problem presents a different quadratic equation and offers multiple-choice answers for the vertex, enhancing understanding of quadratic transformations and vertex form recognition.
