This math topic practices converting quadratic equations from standard form to vertex form, specifically when the coefficient of the quadratic term (a) is negative. The process involves completing the square to rewrite the quadratic expression and determine the vertex (h, k) of the parabola represented by the equation. Each problem presents a quadratic equation with a negative leading coefficient and multiple-choice answers indicating possible vertices. The skill level is introductory and focuses on understanding the transformation of quadratic equations and identifying vertices.
