The video tutorial introduces the concept of the axis of symmetry in quadratic equations. It provides the formula for finding the axis of symmetry, which is x = -b / (2a), and explains how to apply it using an example quadratic equation. The tutorial walks through identifying coefficients a, b, and c, and demonstrates the calculation process, including simplification of the result. The video emphasizes understanding the formula and its application in solving quadratic equations.
