Can i get detailed answer
see... we have (m+5) (m+2) say, (m+5) is ist bracket and (m+2) is second bracket...now, multiply m of ist bracket with m of second bracket we will get m^2 ..then, m of ist bracket with 2 we will get 2 m...now, multiply 5 of ist bracket with m we will get 5 m and then 5 with 2 we will get 10 ....as we know there is a sign of addition so...all these terms will get added and we get m^2+2m+5m+10= m^2+7m+10
