To factor the expression , we can recognize that it represents a difference of cubes.

Step 1: Identify the cubes

We can express as a cube:

, so

 

Thus, we can rewrite the expression as:

 

Step 2: Apply the difference of cubes formula

The difference of cubes can be factored using the formula:

In our case:

a = x

b = 4y

Step 3: Apply the formula

Now we can substitute (a) and (b) into the difference of cubes formula:

First factor:

a - b = x - 4y

 

Second factor:

We need to compute
