Ответ:
(m+n-r)/(m+r-n)
Объяснение:
(m^2+n^2-r^2+2mn)/(m^2-n^2+r^2+2mr) = (m^2+2mn+n^2-r^2)/(m^2+2mr+r^2-n^2)= ((m+n)^2-r^2))/((m+r)^2-n^2)) = ((m+n)-r)(m+n)+r))/((m+r)-n)(m+r)+n))=(m+n-r)/(m+r-n)

Ответ:
(m+n-r)/(m+r-n)
Объяснение:
(m^2+n^2-r^2+2mn)/(m^2-n^2+r^2+2mr) = (m^2+2mn+n^2-r^2)/(m^2+2mr+r^2-n^2)= ((m+n)^2-r^2))/((m+r)^2-n^2)) = ((m+n)-r)(m+n)+r))/((m+r)-n)(m+r)+n))=(m+n-r)/(m+r-n)
