2x^-5x+8/2x^-5x-5=0
则2x^-5x+8=0
2x^-5x-1=-9
则2x^-5x+8=0
2x^-5x-1=-9
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
已知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
|X-1|+|X-2|+|X-3|+|X-4|+|X-5|+|X-6|+|X-7|+|X-8|+|X-9|+|X-10|
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
X-5+8*X=7*X-2*X-1
y=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10)的导数在x=1
设函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10),
(x+12)(x-2)+(x+7)(x+8)-(x+5)(x-10),其中x=2
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
(3-x)/(1-x)-(5-x)/(7-x)+(x^2-x)/(x^2-8x+7)=1
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
