2m﹙m－n﹚²－4m²﹙m－n﹚,坐等,分解因式
2m﹙m－n﹚²－4m²﹙m－n﹚,坐等,分解因式
2m﹙m－n﹚²－4m²﹙m－n﹚,坐等,分解因式
2m﹙m－n﹚²－4m²﹙m－n﹚
=2m(m-n)(1-2m)
2m﹙m－n﹚²－4m²﹙m－n﹚
=m(m-n)[2(m-n)-4m]
=m(m-n)(-2m-2n)
=-2m(m-n)(m+n)
=-2m(m²-n²)
2m﹙m－n﹚²－4m²﹙m－n﹚，
=2m(m-n)(m-n-2m)
=2m(m-n)(-m-n)
=-2m(m-n)(m+n)
2m﹙m－n﹚²－4m²﹙m－n﹚
=m(m-n)[2(m-n)-4m]
=m(m-n)(-2m-2n)
=-2m(m-n)(m+n)
=-2m(m²-n²)
