(-9m^2+4n^2)÷(3m+2n)(-9m^2+4n^2)÷(3m+2n)(-9m^2+4n^2)÷(3m+2n)(-9m^2+4n^2)÷(3m+2n)=(4n^2-9m^2)÷(3m+2n)
(-9m^2+4n^2)÷(3m+2n)
(-9m^2+4n^2)÷(3m+2n)
(-9m^2+4n^2)÷(3m+2n)
(-9m^2+4n^2)÷(3m+2n)
=(4n^2-9m^2)÷(3m+2n)
=(2n+3m)(2n-3m)÷(3m+2n)
=2n-3m
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
[2(m+n)^5-3(m+n)^4+(-m-n)^3]÷[2(m+n)^3]
4m^2(m+n)-9n^2(m+n)
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
4m(m-n)^2+4n(n-m)^3
(m-n)2(n-m)3(n-m)4化简
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
(3m-2n)^+(3m+2n) (3m-2n)-9(m+n)^
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
(3m-4n)(4n+3m)-(2m-n)(2m+n)
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),
若(m-2n)/(2m+n)=3,则[3(m-2n)/(2m+n)-(m-2n)/[2(2m+n)] - {9(m-2n)/[4(2m+n)]}的值是?
【(m+n)(m-n)-(m-n²)+2n(m-n)】÷4n
2(m+n)2-(m+n)+4(m+n)-(m+n)2+3(m+n)2 化简求值
2(m+n)2²-(m+n)+4(m+n)-(m+n)²+3(m+n)² 计算
