分解因式是初中数学的重要内容之一,它与整式乘法运算有着密切的联系,属于整式乘法的逆运算,分解因式变形不仅体现了一种“化归”的思想,而且也是后继内容--分式的化简、解方程等所普遍使用的恒等变形的基础之一,事实上,一个一元n次整式方程anxn+an-1xn-1+…+a2x2+a1x+ao=0的根是否存在问题等价于一元n次多项式anxn+an-1xn-1+…+a2x2+a1x+ao是否能够分解为an(x-b1)(x-b2)…(x一bj)(x2+c1x+d1)…(x2+cix+di)的问题;分式的通分、约分以及异分母的分式相加减,其主要工作就是分
The factor of factorization is one of the important contents of the junior high school mathematics. It is closely related to the integral multiplication operation and belongs to the inverse operation of integer multiplication. Decomposing the factorization not only reflects the idea of “returning to the origin”, but also the successor Content--one of the foundations of constant deformation commonly used in the simplification of fractions, solving equations, etc. In fact, a unitary n-order integral equation anxn+an-1xn-1+...+a2x2+a1x+ao=0 Whether the root of the problem is equivalent to a mononary polynomial anxn+an-1xn-1+...+a2x2+a1x+ao can be decomposed into an(x-b1)(x-b2)...(x-bj)(x2 The problem of +c1x+d1)...(x2+cix+di); the fractional fractions, fractions, and fractions of different denominators are added and subtracted. Their main task is to
