Graphing Quadratics from Factored Form

The video tutorial explains how to work with the factored form of quadratic relations. It covers finding zeros by setting each factor to zero, determining the axis of symmetry using the midpoint formula, and calculating the optimal value by substituting the axis of symmetry into the equation. The tutorial also includes graphing the quadratic equation and solving practice problems to reinforce the concepts.
