m三次方-4m=m三次方n-9mn=3m(2x-y)平方-3mn二次方=m三次方-4m=m三次方n-9mn=3m(2x-y)平方-3mn二次方=m三次方-4m=m三次方n-9mn=3m(2x-y)平方

m三次方-4m= m三次方n-9mn= 3m(2x-y)平方-3mn二次方=
m三次方-4m= m三次方n-9mn= 3m(2x-y)平方-3mn二次方=

m三次方-4m= m三次方n-9mn= 3m(2x-y)平方-3mn二次方=
m三次方-4m=m(m²-4)=m(m+2)(m-2)
.
m三次方n-9mn=mn(m²-9)=mn(m+3)(m-3)
.
3m(2x-y)平方-3mn二次方=3m[(2x-y)²-n²]=3m(2x-y+n)(2x-y-n)
