Solving Quadratic Equations with the Quadratic Formula

The video tutorial explains how to use the quadratic formula to solve for x in quadratic equations. It begins with an introduction to the formula, x = (-b ± √(b² - 4ac)) / 2a, and demonstrates how to substitute values for a, b, and c. An example is provided using the equation 5x² + 8x - 4 = 0, showing step-by-step calculations to find the solutions for x. The tutorial also covers how to plot these solutions on a graph to identify x-intercepts, emphasizing the practical application of the formula in graphing.
