因式分解:(1)a5-a (2)xy2-2xy+xxiexiele
因式分解:(1)a5-a (2)xy2-2xy+x
xiexiele

因式分解:(1)a5-a (2)xy2-2xy+xxiexiele
(1)a^5-a
=a(a^4-1)
=a(a^2+1)(a^2-1)
=a(a^2+1)(a+1)(a-1)
(2)xy2-2xy+x
=x(y^2-2y+1)
=x(y-1)^2

1. a(a^2+1)(a+1)(a-1)
2. x(y-1)^2

1、a(a+1)(a-1)(a2+1)
2、x(y-1)(y-1)

a5-a
=a(a4-1)=a(a2+1)(a+1)(a-1)
xy2-2xy+x
=x(y2-2y+1)
=x(y-1)2
