m^2/3= m*m/3
m*m/3 +2m = m( m/3 +2)
m( m/3 +2)/7
------------------------------------------------
AHORA, en realidad es +3n o es +3m???
----------------------------------------------
Si es mas 3n, entonces:
(m( m/3 +2)+3n)/5 = m*m/15+ 2m/5 +3n/5
Pero si es +3m, entonces:
m( m/3 +2)+3m = m(m/3 +2+3) = m(m/3+5)
m(m/3+5)/5 = m*m/15 + 1
