x^2-10x-1=0

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 4x²+5x=81 x(x+5)=0 (2x-x)(x-1)=0 x(x+5)=5x-10 (3x-2)(x+1)=x(2x-1) 如果X*X--1=0,那么X*X*X+2*X*X+2008=几? 已知x*x+x-1=0 求x*x*x-2x+11=? 已知x*x+x-1=0求x*x*x-2x+2010的值 1/x+1/x(x+1)+1/(x+1)(x+2)+1/(x+2)(x+3)+...1/(x+9)(x+10)=0 解方程:1/x+1/x(x+1)+1/(x+1)(x+2)+1/(x+2)(x+3)+……+1/(x+9)(x+10)=0 （2x-2）(x-1)=0 x(x-5)=5x-10 解方程(x/x(x+2))+(x/(x+2)(x+4))+.+x/(x+8)(x+10)=1 X+X+X+(X-1)+(X-2)+(X-3)+(X-4)=10(X-3)+(X-4) x^4+x^3+x^2+x+1=0,x^2006+x^2005+x^2004+x^2003+x^2002 x*x+2x+x*x+10x+x*x+25+2x+x*x+1+1+16+x*x+4x*x+9-12x+16x*x+4-16x=30x*x-7x-15 求x,可以只要答案.如图,全是正方形,一个边长为1,一个边长为4,求总面积,你也可以用你的方法.上面那个方程是我列的.5x*X+7X-72=0 1/(x^2+2x+10)+1/(x^2+11x+10)+1/(x^2-13x+10)=0 已知x^2-3x+1=0求x^4-5x^3+10x^2-11x+5 x/x-1-2x-2/x-1=0 设f(x)=x(x-1)(x-2)(x-3)...(x-10),则f'(0)等于多少? 6/(x-1)-(x+2)/x(x-1)=0 5/x^2+x - 1/x^2-x=0
