Determinants and Quadratic Equations

The video tutorial explains how to solve a 2x2 determinant and find the value of X. It begins by introducing the problem, which involves solving determinants on both sides of an equation. The tutorial then details the process of solving the determinant by multiplying elements on the principal diagonal and subtracting the product of the secondary diagonal. This leads to forming a quadratic equation, which is solved to find the roots, giving the possible values of X as 3 or 2. The video concludes with a summary of the solution.
