在数学运算中 ,利用因式分解的方法 ,往往使运算由繁化简 ,化难为易 :一、解决计算问题例 1　计算 32 0 0 2 - 5× 32 0 0 1+ 6× 32 0 0 0 + 2 0 0 2 .分析 :前三项含公式 32 0 0 0 ,因此先提公因式后 ,变为简单的计算。解 :原式 =32 0 0 0 ( 32 - 5× 3+ 6) + 2 0 0 0 =32 0 In mathematics operations, the use of factorization methods tends to make operations simple and complex. It is difficult to solve them. First, solve the computational problem. Example 1 Calculation 32 0 0 2 - 5× 32 0 0 1+ 6× 32 0 0 0 + 2 0 0 2 . Analysis: The first three terms contain the formula 30000, so after the common factor is mentioned, it becomes a simple calculation. Solution: Original =32 0 0 0 ( 32 - 5× 3+ 6) + 2 0 0 0 =32 0
