化简:m^2-2m-[(m^2)/2]=16
化简:m^2-2m-[(m^2)/2]=16

化简:m^2-2m-[(m^2)/2]=16
解
两边乘以2
2m²-4m-m²=32
m²-4m=32
m²-4m+4=36
(m-2)²=36
∴m-2=6或m-2=-6
∴m=8或m=-4

m²-2m- m²/2=16
m²/2 -2m -16=0
m²-4m-32=0
(m-8)(m+4)=0
m=8或m=-4

m^2-2m-[(m^2)/2]=16
(m^2)/2-2m=16
m^2-4m=32
(m+4)(m-8)=0
m=-4,或8

化简并求值 m*m*m-2m*m+m除以m*m*m-m 其中m=2011 化简m*m^2*m+m^2*m-m^2*m^2-m^3. 已知m的绝对值=-m 化简|m|-|m-2| (m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)= m-2m-3m+4m-5m-6m+7m.2004m=? (m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=? 已知m*m+m-1=0,求m*m*m+2m*m-2005 m*m-5m-1=0则2m*m-5m+1/m*m 化简(m*m-2m)/(4-m*m) 化简：（2m/m+2-m/m-2）/ （ m/m²—4）=? 已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3| 解方程 2m-m*m 1=2(m*m-2m)(m*m-2m) (m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=? (m^3-m)/(2m+2)化简 化简|m|+|m-1|+|m-2| m(m-3)/2+m化简 m²-m/m+2=_____. 3*9^m*27^m=21^21化简（-m^2)^3除以（m^*m^2)
