-4x^(n-1)-6x^(n+1)
=-2x~(N-1)〈2+3X`~2〉
~代表根号〈〉代表括号
我的做法有点另类 你看看吧
-4x^(n-1)-6x^(n+1)
=-4x^2n+4x^2-6x^2n-6x^2
=-10x^2-2x^2
=-2x^2(5n+1)
-2(x^(n-1))(2+3x^2)
因式分解4x^(n+2)-9x^n+6x^(n-1)-x^(n-2)
因式分解4x^n+2-9x^n+6x^n-1-x^n-2
4x^n+2-9x^n+6x^n-1-x^n-24x^(n+2)-9x^n+6x^(n-1)-x^(n-2),n是整数且大于2
因式分解:x^(2n)+(2x)^(n)+4^(n-1)

(4x^n-2x^n-1-3x^n+2)÷(-5x^n-1)
x^n-1(3x^n+4x^n+1-5x^n+2)
10x^20-6x^n+(x^n+1-9x^2n)-(4x^n+x^n+1)等于多少
f(x)=e^x-x 求证(1/n)^n+(2/n)^n+...+(n/n)^n
x^(n)*x^(n+1)+x^(2n)*x
若(x^2+1/x)^n(n∈N+,n
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)
约分(x^n+2)+(x^n+1)-6x^n/(2x^n+1)+5x^n-(3x^n-1)
(8x^n+1-3x^n-1)-2(-x+9x^n+1-4x^n)=
