4(m+n)^2-9(m-n)^24(m+n)^2-9(m-n)^24(m+n)^2-9(m-n)^24(m+n)²-9(m-n)²=(2m+2n)²-(3m-3n)
4(m+n)^2-9(m-n)^2
4(m+n)^2-9(m-n)^2
4(m+n)^2-9(m-n)^2
4(m + n)² - 9(m - n)²
= (2m + 2n)² - (3m - 3n)²
= (2m + 2n + 3m - 3n)(2m + 2n - 3m + 3n)
= (5m - n)(5n - m)
4m^2(m+n)-9n^2(m+n)
(3m-4n)(4n+3m)-(2m-n)(2m+n)
4(m+n)^2-9(m-n)^2
4(m+n)^2-9(n-m)^2
【(m+n)(m-n)-(m-n²)+2n(m-n)】÷4n
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
(n/m+n/2m^2)*4m/n^2
(m-n)^9乘(n-m)^8/(m-n)^2
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
因式分解4m^2(m-n)+4n(n-m)
