解分式方程(组)的关键是将分式方程转化为整式方程,但对有些分式方程(组),若能根据其结构特征,运用一些技巧,可使解题简捷、准确.一、整体优化,巧用公式
The key to solving fractional equations (groups) is to convert fractional equations into integral equations, but if some fractional equations (groups) can be used according to their structural characteristics, using some techniques, the problem can be solved simply and accurately. Overall optimization, using formulas
