Algebra-2

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

Step 1: Identify the terms

We can rewrite as:

 

Step 2: Apply the difference of cubes formula

The difference of cubes can be factored using the formula:

Where:

(a = 3x)

(b = 1)

 

Step 3: Substitute and calculate

Calculate (a - b):

a - b = 3x - 1

 

Calculate :

 

Calculate (ab):

ab = (3x)(1) = 3x

 

Calculate :
