Find the product of the following :

(a + b) (a2 + 2ab + b2)

Answer :

a(a2 + 2ab + b2) + b(a2 + 2ab + b2)


(a × a2 + a × 2ab + a × b2) + (b × a2 + b × 2ab + b× b2)


(a2 + 1 + 2a1 + 1b + ab2) + (ba2 + 2ab1 + 1 + b2 + 1)


( an + m = an × am)


(a3 + 2a2b + ab2) + (ba2 + 2ab2 + b3)


a3 + 2a2b + a2b + ab2 + 2ab2 + b3


a3 + (2 + 1)a2b + (1 + 2)ab2 + b3


a3 + 3a2b + 3ab2 + b3
