若|x-3|+（y+2）²=0,则（x-y+4xy/x-y）（x+y-4xy/x+y）的值是

若|x-3|+（y+2）²=0,则（x-y+4xy/x-y）（x+y-4xy/x+y）的值是
若|x-3|+（y+2）²=0,则（x-y+4xy/x-y）（x+y-4xy/x+y）的值是

若|x-3|+（y+2）²=0,则（x-y+4xy/x-y）（x+y-4xy/x+y）的值是
由已知得：
X-3=0,
Y+2=0
解得：X=3,Y=-2,
∴原式=［(X-Y)^2+4XY)］/(X-Y)］［(X+Y)^2-4XY］/(X+Y)
=(X+Y)^2(X-Y)^2/［(X-Y)(X+Y)］
=(X+Y)(X-Y)
=X^2-Y^2
=9-4
=5.

x-3=0 y+2=0
x=3 y=-2
(3+2-24/5)(3-2+24/1)=30
