经常阅读《中小学数学》,学到了很多东西.近日读了两篇文章,想和两位作者商榷,也希望同行给予指正.第一个题目是2013年第1-2期朱承华的《数学开放题的教学实践与思考》一文中的例题11:在多项式4x~2+1中添加一个条件,使其成为一个完全平方式,则添加的单项式是——.(只写出一个即可).作者的分析过程和解答过程:要使多项式4x~2+1成为一个完全平方式,可添加一次项,也可添加二次 Often read “primary and secondary mathematics,” learned a lot of things recently read two articles, want to discuss with the two authors, but also hope that colleagues give corrections.The first topic is 2013-2013 Zhu Chenghua’s "mathematical open Example 11: Adding a Condition to Polynomials 4x ~ 2 + 1 to Make it a Completely Flat Equation, then adding the monomial is -. (Just write one.) Authors’ Analytical Process and Solution Process: To make the polynomial 4x ~ 2 + 1 a completely flat type, add a term, or you can add a second
