Step-by-step explanation:
STEP
1  :
Equation at the end of step 1
  (((27•(a3))+((54•(a2))•b))+(36a•(b2)))+23b3
Step 2:
(((27•(a3))+((54•(a2))•b))+(22•32ab2))+23b3
Step 3:
 (((27•(a3))+((2•33a2)•b))+(22•32ab2))+23b3
Step 4:
  ((33a3 +  (2•33a2b)) +  (22•32ab2)) +  23b3
Step 5:
  Factoring:  27a3+54a2b+36ab2+8b3
