Solving a quadratic using quadratic formula with two real solutions

The video tutorial explains how to solve quadratic equations using the quadratic formula. It begins with an introduction to the quadratic formula and its application. The instructor then discusses the importance of expressing the equation in standard form and calculating the discriminant to determine the nature of the solutions. The tutorial proceeds with a step-by-step calculation of the discriminant and explains how to identify whether the solutions are rational or irrational. Finally, the quadratic formula is applied to find the exact solutions, which are then verified and discussed in the context of graphing.
