How do you solve a quadratic by using the square root method

The video tutorial explains how to solve quadratic equations using the square root method. It begins by setting the equation equal to zero to find the x-intercepts. The instructor demonstrates using inverse operations to isolate the variable, followed by applying the square root method to find both positive and negative solutions. Additionally, alternative methods like factoring using the difference of squares are briefly discussed.
