The video tutorial explains how to solve a differential equation using power series methods. It begins by introducing the power series centered at x=0 and differentiating it to find y' and y''. The series is then substituted into the differential equation, and the coefficients are solved using re-indexing and recurrence relations. Zero coefficients are identified, and specific coefficients are calculated. Finally, the power series solution is constructed, demonstrating the method's application.
