Solving a quadratic by completing the square

The video tutorial explains how to solve quadratic equations by completing the square when the coefficient of x^2 is 1. It covers creating a perfect square trinomial, factoring it into a binomial squared, and using inverse operations to solve for x. The tutorial emphasizes keeping fractions instead of converting to decimals for easier calculations. The final solutions are derived by adding and subtracting fractions, resulting in two possible values for x.
