因式分解法解一元二次方程（The factorization method for solving quadratic equation with one unknown） I carefully organize the documents, documents from the network I just sort of If there is an error Please check your! The factorization method for solving quadratic equation with one unknown First, according to teaching materials This section is about the content of the junior middle school mathematics nine grade twenty-second chapter quadratic equation with one unknown unit second drop - solutions of quadratic equation with one unknown section Fourth factorization method Two, design 1, the issue of teaching guiding ideology The design of this class to reflect everyone can obtain the essential mathematics and the guiding ideology of different people have different development in mathematics. From review to practice, try to compare, from design to answer questions Always from simple to complex The introduction of layers Reduce learning gradient So that everyone can learn and everyone has the harvest 2, the issue of teaching design The design of this class in order to fully stir students self discovery, self inquiry, self improvement will introduce the knowledge from the shallower to the deeper. The students are thinking of old problems, find the knowledge and understanding of the new problems in the answer Take the initiative and enthusiasm of students 3, analysis of teaching materials The main contents of this lesson: to factorization reduced solutions of quadratic equation with one unknown The focus is on two times the three type correct decomposition And through practice to induce general steps of the factorization method solutions of quadratic equation with one unknown. We use the factorization method solution of quadratic equation with one unknown and the matters needing attention And let the students learn how to complete factorization by quadratic equation is reduced to a place and pay attention to 4, analysis of the situation The students in this class with the direct metho
