(x+3)(x-2)-(x+1)^2=-1(x+3)(x-2)-(x+1)^2=-1(x+3)(x-2)-(x+1)^2=-1原方程可化为:x^2+x-6-x^2-2x-1=-1-x=6x=-6x^2
(x+3)(x-2)-(x+1)^2=-1
(x+3)(x-2)-(x+1)^2=-1
(x+3)(x-2)-(x+1)^2=-1
原方程可化为:
x^2+x-6-x^2-2x-1=-1
-x=6
x=-6
x^2+x-6-(x^2+2x+1)+1=0
x^2+x-6-x^2-2x-1+1=0
-x-6=0
x=-6
先展开得:x^2+x-6-x^2-2x-1=-1
化简得:-x-7=-1
x=-6
(x+3)(x-2)-(x+1)^2=-1
(x+3)(x-2)-(x+1)^2+1=0
x^2-2x+3x-6-(x^2+2x+1)+1=0
x^2-x^2-2x+3x-2x-6-1+1=0
-x-6=0
x=-6

解下列方程!就三道!解下列方程.1、x/x-2 - 1-x²/x²-5x = 2x/x-3(x/x-2 - 1-x²不是一起的!)2、5x/x²+x-6 - 5-2x/x²-x-12=7x-10/x²-6x+8(5x/x²+x-6 - 5-2x不是一起的!)3、x-4/x-5 + x-8/x-9=x-7/x-

解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
x(x-2)-2x(x+1)-3x(x-5) 其中x=负½
x(x+1)+(x+2)+(x+3)+(x+4)+(x+5) = 27求x
(1)(2x/x-1)-(x-1/x)=1 (2)(x^2-4x/x^2-1)+1=2x/x+1 (3)(x+4/x^2+2x)-(1/x+2)=(2/x)+1
(1)(2x/x-1)-(x-1/x)=1 (2)(x^2-4x/x^2-1)+1=2x/x+1 (3)(x+4/x^2+2x)-(1/x+2)=(2/x)+1
x+5/x+1-3x-3/x+5=8x+28/x^2+4X-5-2(x+5)/(x+1)-(3x-3)/(x+5)=(8x+28)/(x^2+4X-5)-2
