解分式方程的一般方法是通过去分母，化分式方程为整式方程．但这样解有时很繁，而且可能会产生增根．由于某些分式方程在形式结构或数值上都具有一定的特点，如能细心观察、勤于思考，就能找到较好的解题方法，提高我们分析问题、解决问题的能力．例１解方程：分析此方程的特? The general method for solving fractional equations is to de-numerator, and the fractional equation is the integral equation. However, this solution is sometimes very complicated, and it may produce additional roots. Because some fractional equations have certain characteristics in the form of structure or numerical value, if we can observe carefully and diligently think about it, we can find a better solution method and improve our ability to analyze problems and solve problems. Example 1 Solution equation: analysis of this equation?
