I. Teaching Objectives: (1) Knowledge: 1. Make students understand the significance of fractional equations. 2. Define the basic idea of solving fractional equations; Grasp the general steps of the solution of fractional equations; Master how to convert fractional equations into Integral equations; preliminary understanding of the root causes of rooting in solving fractional equations. (b) Capability: Seizing “transformation” and “increasing roots” on the basis of student self-study, helping students read through practice and discussion Communicate teaching materials to develop students’ reading, comparison, analysis, and synthesis skills. Second, the teaching process: (a) The significance of fractional equations: (student answer, teacher summary)
