Solve a quadratic by applying the square root method

The video tutorial explains why the difference of squares method cannot be applied to a given problem and introduces the square root method as an alternative. The instructor demonstrates solving the equation by setting it to zero, using inverse operations, and taking the square root of both sides. The importance of rationalizing the denominator is emphasized to simplify the final answer, ensuring it is not divided by an irrational number. The tutorial concludes with the final solution and a reminder to include both positive and negative roots.
