x÷(x-1)-1=3÷(x-1)(x+2)求求各位大神了x÷(x-1)-1=3÷(x-1)(x+2)求求各位大神了x÷(x-1)-1=3÷(x-1)(x+2)求求各位大神了两边同乘(x-1)(x+2
x÷(x-1)-1=3÷(x-1)(x+2)求求各位大神了
x÷(x-1)-1=3÷(x-1)(x+2)求求各位大神了
x÷(x-1)-1=3÷(x-1)(x+2)求求各位大神了
两边同乘 (x-1)(x+2)
得x(x+2)-(x-1)(x+2)=3
x的平方+2x-(x的平方+x-2)=3
x的平方+2x-x的平方-x+2=3
x+2=3
x=1
经检验,x=1为增根,原分式方程无解
化简 (3x/x-1 -x/x+1)÷x/x²-1
(1-3/x+2)÷x-1/x²+2x-x/x+1,其中x满足x²-x-1=0
已知X²-3x-2=0,求 2x-1 x-1 ----- ÷ -------- 的值 (x- x) x²-2x不能先求X
先化简再求值:(x+2/x²-2x - x-1/x²-4x+4)÷ x-4/x,其中x=3/2
请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
两道初二数学计算题(1)x+6/x^2+2x+1-x+4/x^2+x=0(2)x+3/x÷x^2+3x/x-3·1/3-x
(x-1/x²+6x+9)÷(x²-1/x+3)=(x+1/2)
x*x*x*x+2008x*x+2007x+2008(提示:x*x*x-1=(x-1)*(x*x+x+1))
x^2-1/x^2+4x+4÷(x+1)×x^2+3x+2/x-1计算
[x(x+1)+x平方(x-1)]+(-3x)
x-3/x²-1 ÷ (x-3)(x+1)/x²+2x+1 + 1/x+1,其中x=2
若x=1/x,则(x²2-6x+9)/(x-3)÷(x+3)/(x²+6x+9)的值是
先化简,再求值(2x-6)/(4-4x+x^2)÷ (x+3)× (x^2+x-6)/(3-x),其中x=-1/2
先化简再求值:(x²-4x+4分之x+8-2-x分之1)÷x²-2x分之x+3 x²-4=0
1.(x^3-x^2-4x+1)/(x^2-3x+2)-(x^3-2x^2-9x+21)/(x^2-5x+6)+(x^2-3x+8)/(x^2-4x+3)2.{(x^2)/(x-y)}*{y/(x+y)}-{(x^4y)/(x^4-y^4)}÷{(x^2/x^2+y^2)^2}
先化简,再求值:(1)(x+1/x²-x-x/x²-2x+1)÷1/x,x=根号2+1 (2)(1+x-3/x+3)÷2x/x²-9 x=根号3+3 (3)4-x/x-2÷(x+2-12/x-2)x=根号3-4 (4)x-3/2x-4÷(5/x-2-x-2) x=根号3-2
X×X-3X+1=0求分式X×X÷〈X×X×X×X+3X×X+1〉
X^2-3X-2=0,求( x - 2x-1/x )÷(x-1)/(x^2-2x)
