To factor the expression , we can recognize that it is 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:
For our expression:
(a = 1)
(b = 6x)
Step 3: Substitute and calculate
Calculate (a - b):
a - b = 1 - 6x
Calculate
Calculate (ab):
Calculate
