在数学中,我们常常要把未知的、复杂的研究对象通过适当的方法和手段,转化为熟知的、比较简单的事物,进而使得问题解决.不是吗?利用加减或代人消元,可以把二元一次方程组转化为一元一次方程;借助于添加辅助线,可以将平行四边形、梯形等转化为三角形,以便对它们的特殊性质和判定方法展开研究……当然,转化是多种多样的,既可以是形与数之间的相互转化,也可以是恒等的、放缩的变形,等等.大家知道,把一个多项式化成几个整式的积的 In mathematics, we often turn unknown and complex research objects into appropriate, relatively simple things through appropriate methods and means, so that the problem is solved. Isn’t it? The use of addition and subtraction or generational elimination can be The bivariate equations are transformed into a unitary first-order equation; by adding an auxiliary line, parallelograms, trapezoids, etc. can be converted into triangles so that their special properties and determination methods can be studied... Of course, the transformation is various. , it can be a mutual transformation between form and number, it can also be an equal, deflationary deformation, and so on. Everyone knows that turning a polynomial into a product of several integers
