(m+4n)(m-n)-6(m+2n)(m-3n)
(m+4n)(m-n)-6(m+2n)(m-3n)
(m+4n)(m-n)-6(m+2n)(m-3n)
这是要化简么...
原式=m^2+3mn-4n^2-6(m^2-mn-6n^2)
=-5m^2+9mn+32n^2
计算(m+4n)(m-n)-6(m+2n)(m-3n)
(m+4n)(m-n)-6(m+2n)(m-3n)
(m+4n)(m-n)-6(m+2n)(m-3n),
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
(1),(-m-n)(-m+n) (2),(-m+n)(m-n)
(n/m+n/2m^2)*4m/n^2
因式分解4m^2(m-n)+4n(n-m)
4m(m-n)^2+4n(n-m)^3
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
4m^2(m+n)-9n^2(m+n)
(m-n)2(n-m)3(n-m)4化简
(m-2n)(-m-n)
化简,1.[(m+n-p)(m+p+n)-(m+n)²]/(-p),2.[(m+n)(m-n)-(m-n)²+2n(m-n)]/4n
(m-n)^6除以(n-m)^4
6(m+n)²-2(m+n)
(m-n)^2*(m-n)^4=?
4m(m-m)-2n(n-m)
