(X^5- 6X^3 + 7X^2 -7X + 3)/(X^2 -2X +1)
分母=（X-1）^2
分子=X^3*(X^2-1)-5*X^3+7*X^2-7*X+3
=X^3*(X^2-1)-5*X^2*(X-1)+2*X^2-7*X+3
=X^3*(X^2-1)-5*X^2*(X-1)+2*X*(X-1)-5*X+3
=X^3*(X^2-1)-5*X^2*(X-1)+2*X*(X-1)-5*(X-1)-2
原式=[X^3*(X+1)-5*X^2-2*X-5]/(X-1)-2/(X-1)^2
左式分子=X^4+X^3-5*X^2-2*X-5
=>X^3*（X-1）+2*X^2*(X-1)-3*X*(X-1)-5(X-1)-10
=>左式=X^3+2*X^2-3*X-5-10/(X-1)=X^2*(X-1)+3*X*(X-1)-5-10/(X-1)
原式=X^2*(X-1)+3*X*(X-1)-5-10/(X-1))-2/(X-1)^2
就化简到这吧,累死我了!

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^5+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),
2x+3x+4x+5x+x+6x+7x=100
解方程(x+1/x+2)-(x+2/x+3)=(x+5/x+6)-(x+6/x+7)
解方程：x+2/x+1-x+3/x+2=x+6/x+5-x+7/x+6
x-1\x-2+x-6\x-7=x-2\x-3+x-5\x-6 分式方程
（1） x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
1x+2x+3x+4x+5x+6x+7x…+99x=100
(X+2)/(X+1)-(X+4)/(X+3)=(X+6)/(X+5)-(X+8)/(X+7)
