(m-n)^2-10(n-m)+25得多少(m-n)^2-10(n-m)+25得多少(m-n)^2-10(n-m)+25得多少(m-n)^2-10(n-m)+25=(m-n)^2+10(m-n)+25

(m-n)^2-10(n-m)+25得多少
(m-n)^2-10(n-m)+25得多少

(m-n)^2-10(n-m)+25得多少
(m-n)^2-10(n-m)+25
=(m-n)^2+10(m-n)+25
=(m-n)^2+5(m-n)+5(m-n)+25
=(m-n)(m-n+5)+5(m-n+5)
=(m-n+5)^2

(m-n)^2-10(n-m)+25
=(m-n)^2+2*5*(m-n)+25
=(m-n+5)^2

(m-n)^2-10(n-m)+25
=(m-n)^2+10(m-n)+25
=(m-n+5)^5

(n-m-5)^2
