Find the cube of each of the following binomial expressions:

(i)


(ii)


(iii)


(iv)

(i) Using the identity, (a+b)3 = a3 + b3 + 3a2 b + 3ab2

We will write the bionomial expression,



(ii) Using the identity, (a-b)3 = a3 - b3 - 3a2 b + 3ab2


We will write the bionomial expression,



(iii) Using the identity, (a-b)3 = a3 - b3 - 3a2 b + 3ab2


We will write the bionomial expression,



(iv) Using the identity, (a-b)3 = a3 - b3 - 3a2 b + 3ab2


We will write the bionomial expression,
