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
设f(x)=x㏑(1+x^2),x≥0.(x^2+2x-3)e^(-x),x<0,求∫f(x)dx
已知1/√(x)+√(x)=√5,求√(x/x2+x+1)+√(x/x2-x+1)的值定义域 x>0,两边平方,x+2+1/x=5,x+1/x=3,x^2-3x+1=0,x^2+x+1-4x=0,x^2+x+1=4x,x^2-x+1-2x=0.x^2-x+1=2x,√[x/(x^2+x+1)]-√[x/(x^2-x+1)]=√[x/(4x)]-√[x/2x]=√(1/4)-√(1/2)
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+2010的值
已知x*x+x-1=0 求x*x*x-2x+11=?
x^4+x^3+x^2+x+1=0,x^2006+x^2005+x^2004+x^2003+x^2002
2x/0.03+0.25-0,1x/0.02=0.1
lim(1-x)^(2/x) x->0
x>0,x- (x)/(2x+1) + (2x+1)/(x) 的最小值是多少?x>0,x- (x)/(2x+1) + (2x+1)/(x^2)才对。
