平方差公式是初中整式乘法中的一个重要内容 ,它是多项式乘法中的一种特例 ,是对多项式乘法的一个必要补充 ,同时还是以后学习因式分解的基础 .因此 ,对于如何学好平方差公式一直是学生想要解决的问题 .本人结合在教学中的体会 ,谈一下自己的看法 ,供同学们参考 .一、要了解平 The square difference formula is an important part of the multiplication of polynomials in the junior high school. It is a special case of polynomial multiplication. It is a necessary supplement to polynomial multiplication, and it is also the basis for learning factorization later. Therefore, how to learn the square difference formula Has always been a problem that students want to solve. I combine the experience in teaching and talk about my own views for the students to refer to. I. To understand
