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-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3)
x(x+1)+(x+2)+(x+3)+(x+4)+(x+5) = 27求x
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=?
写过程x(x-1)+2x(x+1)-3x(2x-5)-x(3x-2)+2x(2-x)=-5x(x-2)-4
x^4+x^3+x^2+x+1=0,x^2006+x^2005+x^2004+x^2003+x^2002
x+2/x+1-x+3/x+2-x+4/x+3+x+5/x+4
(x+1)(x+2)(x+3)(x+4)=24
(x-1)(x-2)(x-3)(x-4)=48
(x+1)(x+2)(x+3)(x+4)=24
x-1+x+2+x/3+4x=77
x^5-x^4+x^3-x^2+x-1
(X+1)X(X+2)X(X+3)=504
先化简,再求值:(2-x/x^2+x)/(x^2-3x/x^2+2x+1)x(9-x^2/4-2x),其中x=-2
解方程(x+1/x-1)+(x-2/x+2)+(x-3/x+3)+(x+4/x-4)=4
x*2-4x+4/(x*-9)]/[x*-4/(x*2+3x)]/(1/3)x 其中x=-1
