(-x)^5÷x^2
(x^-3x+2/x^-5x+6)^2÷(x-1/x^2-2x-3)^2
化简：[(x+2)/(x^2-4)-(2x-5)/(x-4x+4)]÷[(x-3)/(x-2)]
1.(x^3-x^2-4x+1)/(x^2-3x+2)-(x^3-2x^2-9x+21)/（x^2-5x+6）+（x^2-3x+8）/（x^2-4x+3）2.{(x^2)/（x-y)}*{y/(x+y)}-{(x^4y)/(x^4-y^4)}÷{（x^2/x^2+y^2）^2}
化简：〔（x^2+18x+72)÷（x+12)-(x^2+5x-6)÷(x-1)〕·(x^3-2x^2-x+1)

(x+3x+5x...+2009x)-(2x+4x+6x+...+2010x)
16-x^2/x^2-2x-3÷1^2-5x+4/x-3
计算：(1)/(x-3)÷(x+2)/(x^2-9)-(1)/(x^2+5x+6)
化简：x^2-5x+6/x^2-1÷x-3/x+1
(-x^2n-2)*(-x)^5÷[x^n+1*x^n*(-x)]=?
