请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
(X-3分之x-1-x分之x-4)除以x的平方+3x分之(x+3)(x-2),其中(x-1)(x-2)=0
[x(x+1)+x平方(x-1)]+(-3x)
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-
(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
x^2-1/x^2+4x+4÷(x+1)×x^2+3x+2/x-1计算
(x+2分之3x-x+2分之x)/x平方-4分之x(x-1)=4
2x-6/4-4x+x^2/(x+2)*x^2-4/3-x,其中x=-1
[(2x+6)/(x^2-4x+4)]×[(x-2)/(x^2+3x)]-1/x-2化简!
x(x+1)(x+2)(x+3)+1 (换元法)
