1.化简1/x(x-1)+1/(x-1)(x-2)+1/(x-2)(x-3)+…+1/(x-9)(x-10)= 一定要写
x^2+2x/3x^2+x-10化简
1.(x-2)(x+2)-(x+1)(x-3)
1.x(x+1)(x+2)(x+3)+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),
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
X+7/X+1+X+8/X+2-X+9/X+3-X+10/X+4 的解法
1.通分3x/x+1,2x+6/x,x方-9/x-1
1.x/9+x=62.x/x+1 + x+1/2x = 3
