Harshit Singh5 Years agoDear StudentWhen term have the same algebraic factors, they are like terms.Then, we have to add the like terms= - 7mn + 5 + 12mn + 2 + (9mn - 8) + (- 2mn - 3)= - 7mn + 5 + 12mn + 2 + 9mn–8 - 2mn - 3= - 7mn + 12mn + 9mn–2mn + 5 + 2–8–3= mn (-7 + 12 + 9 - 2) + (5 + 2–8 - 3)= mn (- 9 + 21) + (7 - 11) = mn (12)–4= 12mn - 4Thanks
