(3a2 + 2ab + 2b) + (5a2 − 3ab + 9)

ivann1987 [24]

Step-by-step explanation:

$\tt{(3 {a}^{2} + 2ab + 2b) + (5 {a}^{2} - 3ab + 9})$

~While adding , the sign of each term of second expression remains same. So, Remove the unnecessary parentheses :

⤑ $\tt{3 {a}^{2} + 2ab + 2b + 5 {a}^{2} - 3ab + 9}$

~Like terms are those which have the same base. Combine the like terms :

⤑ $\tt{3 {a}^{2} + 5 {a}^{2} + 2ab - 3ab + 2b + 9}$

⤑ $\sf{8 {a}^{2} - ab + 2b + 9}$

$\red{ \boxed{ \boxed{ \tt{ ⟿ Our \: final \: answer : 8 {a}^{2} - ab + 2b + 9}}}}$

Hope I helped ! ツ

Have a wonderful day / night ♡
