用mathematics算算32x^5+16x^4-32x^3-12x^2+6x+1=0
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
2x(7-3x)+5x(2x+1)=x(4x-3)+32
1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
|X-1|+|X-2|+|X-3|+|X-4|+|X-5|+|X-6|+|X-7|+|X-8|+|X-9|+|X-10|
x/x-4 - 32/x的平方+16=1 x+1/x + 5X/x+1=6
若2x-3y+4=0则x(x*x-1)+x(5-x*x)-6y+7
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
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
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),
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
