联想思维是一种重要的创造性思维方法.在数学解题实践中更是一种重要的思维方法.现例举如下: 例1 已知x/x2+x+1=a(a≠0,a≠1/2),求x2/x4+x2+1的值.
Associative thinking is an important creative thinking method. In mathematics problem solving practice, it is an important thinking method. Here are some examples: Example 1 Known x/x2+x+1=a (a≠0,a) ≠ 1/2), find the value of x2/x4+x2+1.
