计算(m^2-9)/[m(m-3)+m-3]计算(m^2-9)/[m(m-3)+m-3]计算(m^2-9)/[m(m-3)+m-3](m^2-9)/[m(m-3)+m-3]=(m+3)(m-3)/[(

计算(m^2-9)/[m(m-3)+m-3]
计算(m^2-9)/[m(m-3)+m-3]

计算(m^2-9)/[m(m-3)+m-3]
(m^2-9)/[m(m-3)+m-3]
=(m+3)(m-3)/[(m+1)(m-3)]
=(m+3)/(m+1)

原式=(m+3)(m-3)/[(m-3)(m+1)]
=(m+3)/(m+1)

原式=(m+3)(m-3)/(m+1)(m-3)
=(m+3)/(m+1)

(m^2-9)/[m(m-3)+m-3]
=(m+3)(m-3)/(m-3)(m+1)
=(m+3)/(m+1)
