Algebra-2

To factor the expression , we can recognize that it is a sum of cubes.

Step 1: Identify the terms

We can rewrite  as:

 

Step 2: Apply the sum of cubes formula

The sum of cubes can be factored using the formula:

For our expression:

(a = 8x)

(b = 7)

 

Step 3: Substitute and calculate

Calculate (a + b):

a + b = 8x + 7

 

Calculate

 

Calculate (ab):

ab = (8x)(7) = 56x

 

Calculate
