The video tutorial explains how to determine the vertex and X intercepts of a quadratic equation in vertex form. It covers identifying the vertex using the formula y = a * (X - H)^2 + K, where the vertex is (H, K). The tutorial also demonstrates finding the X intercepts by solving the equation when it equals zero, using the square root method and inverse operations. The process involves isolating the squared term, applying the square root, and considering both positive and negative solutions. The tutorial concludes with a recap of the steps to find the vertex and X intercepts.
