所谓配方,就是把一个解析式利用恒等变形的方法,把其中的某些项配成一个或几个多项式正整数次幂的和形式.通过配方解决数学问题的方法叫配方法,其中,用的最多的是配成完全平方式,即利用完全平方公式a2±2ab+b2=(a±b)2把一个解析式写成平方的形式.配方法是数学中一种重要的恒等变形的方法,它的应用非常广泛,在因式分解、化简根式、解方程、证明等式和不等式、求函数的极值和解析式等方面都经常用到 The so-called formula, is to use an analytical method of equal deformation, some of which are assigned to one or several polynomials and a positive integer power sum formula method to solve mathematical problems called method, in which the use of Is the most complete with a flat form, that is, the use of a complete square formula a2 ± 2ab + b2 = (a ± b) 2 to a analytical form of the square formula method is an important mathematical method of equal deformation , It is widely used in factoring, simplifying roots, solving equations, proving equations and inequalities, finding extremums and resolving equations of functions are often used
