2x*x+3x-12=0

x/(x-2)-x/(x+3)=2文章源自玩技e族-https://www.playezu.com/247802.html

解：x/(x-2)-x/(x+3)=2文章源自玩技e族-https://www.playezu.com/247802.html

X*（1/（X-2）-1/（X+3）=2文章源自玩技e族-https://www.playezu.com/247802.html

X*（X+3-X+2）/（（X-2）*（X+3））=2文章源自玩技e族-https://www.playezu.com/247802.html

5X=2*（X-2）*（X+3）文章源自玩技e族-https://www.playezu.com/247802.html

5X=2X*X+2X-12文章源自玩技e族-https://www.playezu.com/247802.html

2X*X-3X-12=0文章源自玩技e族-https://www.playezu.com/247802.html

剩下的方程就你自己解了吧。文章源自玩技e族-https://www.playezu.com/247802.html

x/(x-2)-x/(x+3)=2文章源自玩技e族-https://www.playezu.com/247802.html

解：方程两边同时乘（x-2)(x=3)文章源自玩技e族-https://www.playezu.com/247802.html

x*（x+3）-x*(x-2)=2(x-2)(x+3)

2x的二次方-3x-12=0

x=(3加减根号105）/4
