当m=时,2m(3m-5)+3m(1-2m)=14当m=时,2m(3m-5)+3m(1-2m)=14当m=时,2m(3m-5)+3m(1-2m)=142m(3m-5)+3m(1-2m)=146m^2-

当m= 时,2m(3m-5)+3m(1-2m)=14
当m= 时,2m(3m-5)+3m(1-2m)=14

当m= 时,2m(3m-5)+3m(1-2m)=14
2m(3m-5)+3m(1-2m)=14
6m^2-10m+3m-6m^2=14
-7m=14
m=-2

-2

-2

-2

6m^2-10m+3m-6m^2=14
-7m=14
m=-2

m= -2

根据公式可得6m²-10m+3m-6m²=14 → -7m=14 →m=-2

m=-2;展开就可以知道是一个一元一次方程。
