The video tutorial explains how to find the axis of symmetry and vertex of a quadratic equation. It begins with an introduction to the quadratic form and the importance of understanding the coefficients. The tutorial then details the steps to calculate the axis of symmetry using the formula -B/2A and demonstrates how to find the vertex by substituting the axis of symmetry into the equation. The example used has coefficients A=6, B=0, and C=0, leading to an axis of symmetry at X=0 and a vertex at (0,0).
