About This Lesson
http://www.freemathvideos.com In this video series I show you how to find the solutions of a quadratic equation by applying the quadratic formula. When using the quadratic formula we first determine the parts of the equation and determine the value of the discriminat to determine the number and types of solutions. This is helpful to know and understand about your solution. we then plug in the values from our equation into the formula and solve for the values of x which are our solutions and x-intercepts of the graph.
Great resource for absent or struggling students.
