分式加减题1/(m^2-m)+(m-5)/(2m^2-2)分式加减题1/(m^2-m)+(m-5)/(2m^2-2)分式加减题1/(m^2-m)+(m-5)/(2m^2-2)1/(m^2-m)+(m-

分式加减题1/(m^2-m)+(m-5)/(2m^2-2)
分式加减题
1/(m^2-m)+(m-5)/(2m^2-2)

分式加减题1/(m^2-m)+(m-5)/(2m^2-2)
1/(m^2-m)+(m-5)/(2m^2-2)
=1/m(m-1) +(m-5）/2(m-1)(m+1)
=(2m+2+m^2-5m)/2m(m-1)(m+1)
=(m^2-3m+2)/2m(m-1)(m+1)
=(m-1)(m-2)/2m(m-1)(m+1)
=(m-2)/2m(m+1)
