x-y/2x+2y与xy/(x+y)^2 初二通分题 两道 100财富
x-y/2x+2y与xy/(x+y)^2 2mn/4m^2-9与2m-3/2m+3
x-y/2x+2y与xy/(x+y)^2 2mn/4m^2-9与2m-3/2m+3
x-y/2x+2y与xy/(x+y)^2
2x+2y与(x+y)^2的最小公倍数是2(x+y)^2
x-y/2x+2y=x-y/2(x+y)=(x-y)(x+y)/2(x+y)^2=x^2-y^2/2(x+y)^2
xy/(x+y)^2=2xy/2(x+y)^2
2.2mn/4m^2-9与2m-3/2m+3
4m^2-9=(2m)^2-3^2=（2m+3）(2m-3)与2m+3的最小公倍数是4m^2-9
2mn/4m^2-9
2m-3/2m+3=(2m-3)^2/（2m+3）(2m-3)=(2m-3)^2/4m^2-9
2x+2y与(x+y)^2的最小公倍数是2(x+y)^2
x-y/2x+2y=x-y/2(x+y)=(x-y)(x+y)/2(x+y)^2=x^2-y^2/2(x+y)^2
xy/(x+y)^2=2xy/2(x+y)^2
2.2mn/4m^2-9与2m-3/2m+3
4m^2-9=(2m)^2-3^2=（2m+3）(2m-3)与2m+3的最小公倍数是4m^2-9
2mn/4m^2-9
2m-3/2m+3=(2m-3)^2/（2m+3）(2m-3)=(2m-3)^2/4m^2-9
