The video tutorial explains how to find the X intercepts of a polynomial equation. It begins by identifying the components A, B, and C of the polynomial equation X^2 - X - 12 = 0. The teacher then demonstrates factoring the polynomial into two binomials and solving for the X intercepts using the Zero Product Property. The X intercepts are found to be X = 4 and X = -3, where the graph crosses the X-axis.
