Algebra-2

To factor the expression , we can follow a similar approach as in the previous example. First, we rewrite (-1) in a form that allows us to combine the terms. We can express (-1) as :

 

Now, we can factor out :

 

Next, we recognize that (27) is (since ), and we can rewrite the expression as:

 

Now we can factor using the sum of cubes formula:
