Finding Zeros of Quadratic Equations

The video tutorial explains how to find the zeros of a quadratic equation using the Diamond Method and the zero product property. It begins by identifying the coefficients A, B, and C, then applies the Diamond Method to find factors that multiply to give the product of A and C and add to give B. The equation is factored into binomials, and common factors are removed. Finally, the zero product property is used to find the solutions of the equation.
