2(x+1)^2/(x^2)+(x+1)/(x)-6=0 解方程
2(x+1)^2/(x^2)+(x+1)/(x)-6=0 解方程
2(x+1)^2/(x^2)+(x+1)/(x)-6=0 解方程
2(x+1)^2/(x^2)+(x+1)/(x)-6=0 两边乘x^2
2(x+1)^2+x(x+1)-6x^2=0
2x^2+4x+2+x^2+x-6x^2=0
-3x^2+5x+2=0
3x^2-5x-2=0
(3x+1)(x-2)=0
x1=-1/3 x2=2
x1=-1/3 x2=2
2(x+1)^2+x(x+1)-6x^2=0
2x^2+4x+2+x^2+x-6x^2=0
-3x^2+5x+2=0
3x^2-5x-2=0
(3x+1)(x-2)=0
x1=-1/3 x2=2
设（x+1）/(x)=a
则2a^2+a-6=o
(2a-3)(a+2)=0
a=3/2或a=-2
(x+1)/x=-2时x=-1/3
(x+1)/x=3/2时x=2
总队上所述，x=-1/3或2
lz，2(x+1)^2+x(x+1)-6x^2=0
2x^2+4x+2+x^2+x-6x^2=0
-3x^2+5x+2=0
3x^2-5x-2=0
(3x+1)(x-2)=0
x1=-1/3 x2=2
