X+X-1/2-3-X/3=0x=?X+X-1/2-3-X/3=0x=?X+X-1/2-3-X/3=0x=?两边乘66x+3(x-1)-2(3-x)=06x+3x-3-6+2x=06x+3x+2x=3
X+X-1/2-3-X/3=0 x=?
X+X-1/2-3-X/3=0 x=?
X+X-1/2-3-X/3=0 x=?
两边乘6
6x+3(x-1)-2(3-x)=0
6x+3x-3-6+2x=0
6x+3x+2x=3+6
11x=9
x=9/11
一个“整式的乘法”的问题请先阅读下列解题过程,再仿做下面的问题.已知X*X + X - 1=0,求X*X*X + 2*X*X + 3的值.解X*X*X + 2X*X +3=X*X*X +X*X -X +X*X +X +3=X{X*X +X -1} +X*X +X -1 +4=0+0+4=4+ x + X*X + X*X*X=0.+ X*X + X*X*X
x^4+x^3+x^2+x+1=0,x^2006+x^2005+x^2004+x^2003+x^2002
(X+1)X(X+2)X(X+3)=504
(x+2)(x-3)(x-6)(x-1)=0
已知1+x+x^2+x^3=0,求x+x^2+x^3+x^4+x^+x^6+x^7+x^8的值
如果1+x+x^2+x^3=0,求x+x^2+X^3+x^4+x^5+x^6+x^7+x^8的值,
1/(x*x-2x-3)+2/(x*-x-6)+3/(x*x+3x+2)=0
已知X^2-X-1=0,则-X^3+2X+2006X^*X为什么=X^2+X
X^2-3X-2=0,求( x - 2x-1/x )÷(x-1)/(x^2-2x)
已知x*x-3x+1=0求√(x*x+1/x-2)=?
已知x^-x-1=0,求x^4+x^3-x^2-4x+3
(x-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3)
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
请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
X+X+X+(X-1)+(X-2)+(X-3)+(X-4)=10(X-3)+(X-4)
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
