化简:(1-3m)/2-(2m+5)/3+(3+2m)/4化简:(1-3m)/2-(2m+5)/3+(3+2m)/4化简:(1-3m)/2-(2m+5)/3+(3+2m)/4(1-3m)/2-(2m+
化简:(1-3m)/2 - (2m+5)/3 + (3+2m)/4
化简:(1-3m)/2 - (2m+5)/3 + (3+2m)/4
化简:(1-3m)/2 - (2m+5)/3 + (3+2m)/4
(1-3m)/2 - (2m+5)/3 + (3+2m)/4
=[6(1-3m)-4(2m+5)+3(3+2m)]/12
=(-5-20m)/12
=-(5+20m)/12
已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
