因式分解:2m^2n-m^3-mn^2
因式分解:2m^2n-m^3-mn^2

因式分解:2m^2n-m^3-mn^2
2m^2n-m^3-mn^2
= m(2mn - m² - n²)
= -m(m² + n² - 2mn)
= -m(m - n)²

=m(2mn-m^2-n^2)
=-m(m-n)^2

2m^2n-m^3-mn^2
=m(2mn-m^2-n^2)
=-m(m-n)^2

2m^2n-m^3-mn^2
=m(2mn-m^2-n^2)
=-m(m-n)^2

2m^2n-m^3-mn^2=m(2mn-m^2-n^2)=-m(m^2-2mn+n^2)=-m(m-n)^2

2m^2n-m^3-mn^2=-m(-2mn+m^2+n^2)
=-m(n-m)^2或m(m-n)(n-m)
