因式分解:x^9+x^8-x^6-x^5+x^3+x^2-1因式分解:x^9+x^8-x^6-x^5+x^3+x^2-1因式分解:x^9+x^8-x^6-x^5+x^3+x^2-1=x^6(x^3-1

因式分解:x^9+x^8-x^6-x^5+x^3+x^2-1
因式分解:x^9+x^8-x^6-x^5+x^3+x^2-1

因式分解:x^9+x^8-x^6-x^5+x^3+x^2-1
=x^6(x^3-1)+x^5(x^3-1)+(x^3-1)+x^2
=(x^3-1)(x^6+x^5+1)+x^2

=x^6(x^3-1)+x^5(x^3-1)+(x^3-1)+x^2
=(x^3-1)(x^6+x^5+1)+x^2
