因式分解:(1)n²(m-2)-n(2-m) (2)x³-6x²+9x
因式分解:(1)n²(m-2)-n(2-m) (2)x³-6x²+9x

因式分解:(1)n²(m-2)-n(2-m) (2)x³-6x²+9x
(1)n²(m-2)-n(2-m)
=n²(m-2)+n(m-2)
=n(m-2)(n+1)
(2)x³-6x²+9x
=x(x²-6x+9)
=x(x-3)²

n²(m-2)-n(2-m)
=n²(m-2)+n(m-2)
=(n²+n)(m-2)
=n(n+1)(m-2)

x³-6x²+9x
=x(x²-6x+9)
=x(x-3)²

(1)n²(m-2)-n(2-m)
=n²(m-2)+n(m-2)
=n(m-2)(n+1)
(2)x³-6x²+9x
=x(x²-6x+9)
=x(x-3)²

n(m-2)(n+1) x(x-3)^2
