x^3n-x^2n-x^n+1(ax+by)^2+(ab-xy)^2怎么因式分解（要详细过程）x^3n-x^2n-x^n+1(ax+by)^2+(ab-xy)^2怎么因式分解（要详细过程）x^3n-x

x^3n-x^2n-x^n+1 (ax+by)^2+(ab-xy)^2怎么因式分解（要详细过程）
x^3n-x^2n-x^n+1
(ax+by)^2+(ab-xy)^2
怎么因式分解（要详细过程）

x^3n-x^2n-x^n+1 (ax+by)^2+(ab-xy)^2怎么因式分解（要详细过程）
x^3n-x^2n-x^n+1
=x^3n+1-x^n*(x^n+1)
=(x^n+1)(x^2n-x^n+1)-x^n*(x^n+1)
=(x^n+1)(x^2n-1)^2
(ax+by)^2+(ab-xy)^2
=a^2x^2+2abxy+b^2y^2+a^2b^2-2abxy+x^2y^2
=a^2x^2+b^2y^2+a^2b^2+x^2y^2
=a^2(x^2+b^2)+y^2(x^2+b^2)
=(a^2+y^2)(x^2+b^2)

3ax^n+1-6a^2x^n+3a^2x^n-1因式分解 x^n*x^n+1*(-x)^2n*x+(-x)^2n+3x^2n-2*x f(x)=e^x-x 求证(1/n)^n+(2/n)^n+...+(n/n)^n (-x)^3x^n-1+x^2n(-x)^3 x^(n)*x^(n+1)+x^(2n)*x (4x^n-2x^n-1-3x^n+2)÷（-5x^n-1) 计算(x^(2n)+x^n+1)(x^(3n)-x^(2n)+1) x^n-1(3x^n+4x^n+1-5x^n+2) 若(x^2+1/x)^n(n∈N+,n 因式分解：9a^2+x^2n+6a+2x^n+6ax^n+1 9a^2+x^2n+6a+2x^n+6ax^n+1 因式分解已知(Ax^2n-1)=x^3n(x≠0）,则A=? 因式分解：(x^n+1)+(2x^n)+(x^n-1) x^n+1-2x^n+x^n-1因式分解 x^n-1-2x^n+x^n-1因式分解分解因式x^n-x^(n-1)+x^(n-2) 因式分解:3ax^n+1-6a^2x^n+3a^3x^n-1kkkkkkkk 最好现在设集合M={x|x=2n+1,n∈N},N={x|x=3n,n∈N},则M∩N=
