How could you use polynomial identities to factor the expression  .

The correct answer is: We can use multiple identities to simplify or factorize a polynomial fraction.

ANSWER:
Hint:

Here, a and b can be real numbers, variables or multiples of both.
We are asked to explain on how to use polynomial identities to factorize the given expression.
Step 1 of 3:
Factorization of algebraic means to obtain two or more expressions whose product is the given expression. The process of finding two or more expressions whose product is the given expression is called the factorization of algebraic expressions.
Step 2 of 3:


Step 3 of 3:
Now, apply the identity of cubes to the simplified expression. Thus, we get:

Thus, the factorized form is:

Note:
We can use multiple identities to simplify or factorize a polynomial fraction.
