一、分解不彻底例1分解因式:16x~4-y~4.错解16x~4=(4x~2+y~2)(4x~2-y~2).分析结果分解不彻底,因式(4x~2-y~2)还能继续分解,应分解到不能再分解为止.
First, the decomposition is not complete Example 1 factorization formula: 16x ~ 4-y ~ 4. Decomposition 16x ~ 4 = (4x ~ 2 + y ~ 2) (4x ~ 2-y ~ 2) Analysis results are not completely broken down, Factor (4x ~ 2-y ~ 2) can continue to decompose, should be decomposed so can not be decomposed so far.
