m-2n+m^2-4n^2因式分解.m-2n+m^2-4n^2因式分解.m-2n+m^2-4n^2因式分解.m-2n+m^2-4n^2=(m-2n)+(m-2n)(m+2n)=(m-2n)(1+m+2

m-2n+m^2-4n^2因式分解.
m-2n+m^2-4n^2因式分解.

m-2n+m^2-4n^2因式分解.
m-2n+m^2-4n^2
=(m-2n)+(m-2n)(m+2n)
=(m-2n)(1+m+2n)
=(m-2n)(m+2n+1)

你好
m-2n+m^2-4n^2
=(m-2n)+(m-2n)(m+2n)
=(m-2n)(m+2n+1)
数学辅导团为您解答,不理解请追问,理解请及时选为满意回答!(*^__^*)谢谢!

m-2n+m^2-4n^2=(m+1/2)^2-4(n+1/4)^2
=[(m+1/2)+2(n+1/4)][(m+1/2)-2(n+1/4)]
=(m+2n+1)(m-2n)

(m+2n+1)×(m-2n)
