贵刊在2006年第6期刊登了一篇题为《一个等式变形,解决一类整数问题》的文章,笔者认为该文作者探究问题的精神和研究问题的方法非常宝贵,值得我们学习；同时笔者认为对于文中所谈的axy+bx+cy+d=0(a≠0,且a、b、c、d为已知整数)型的整数问题,采取逆用多项式的乘法,构造两个一次因式之积的方法来处理,读者不仅容易理解,而且容易掌握．现举例说明如下． In your issue 6 of 2006, your magazine published an article titled “A Equality Transformation to Solve a Class of Integer Problems”. The author believes that the author’s exploration of the spirit of the problem and the method of researching the issue are invaluable and worthy of our study; At the same time, the author thinks that for the integer problem of the type axy+bx+cy+d=0 (a≠0 and a, b, c, and d are known integers) discussed in the text, the inverse multinomial multiplication is used to construct two integers. A way to deal with the product of the method, the reader is not only easy to understand, but also easy to grasp. An example is illustrated below.
