若|m-3|+n^2-4n+4=0求[(2m+n)^2-3(m+n)(m-n)-4n^2]/(-1/4m)的值今天就要若|m-3|+n^2-4n+4=0求[(2m+n)^2-3(m+n)(m-n)-4

若|m-3|+n^2-4n+4=0求[(2m+n)^2-3(m+n)(m-n)-4n^2]/(-1/4m)的值今天就要
若|m-3|+n^2-4n+4=0求[(2m+n)^2-3(m+n)(m-n)-4n^2]/(-1/4m)的值
今天就要

若|m-3|+n^2-4n+4=0求[(2m+n)^2-3(m+n)(m-n)-4n^2]/(-1/4m)的值今天就要
即|m-3|+(n-2)²=0
所以m-3=n-2=0
m=3,n=2
原式=(4m²+4mn+n²-3m²+3n²-4n²)/(-1/4m)
=(m²+4mn)/(-1/4m)
=-4m-16n
=-12-32
=-44

|m－3|＋(n－2)²=0，则：
m－3=0且n－2=0，得：m=3、n=2
则：
原式=[(4m²＋4mn＋n²)－3(m²－n²)－4n²]/(－1/4m)
=[m²＋4mn]/(－1/4m)
=－4(m＋4n)
=－44

|m-3|+n^2-4n+4=0
|m-3|+（n-2）^2=0
|m-3|>=0 （n-2）^2>=0
即m=3 n=2
代入式子得
[(2m+n)^2-3(m+n)(m-n)-4n^2]/(-1/4m)
=[(6+2)^2-3(3+2)(3-2)-16]/(-1/12)
=[64-15-16]/(-1/12)
=33X(-12)
=-396
