The video tutorial explains solving a quadratic equation that cannot be factored by using the quadratic formula. It begins by identifying the coefficients and calculating the discriminant to determine the nature of the solutions. Since the discriminant is negative, the equation has complex solutions. The tutorial then simplifies the quadratic formula to find these solutions, emphasizing the use of imaginary numbers. The lesson concludes with a summary of the process.
