Question 1139471: Sum or Difference of​ Cubes:
Example 3.Fill in the parts of the​ step-by-step process of factoring a difference of cubes.
We want to factor x^3-8
Step​ 1: Is this a sum or difference of​ cubes? Y or​ N?___
If​ Yes, construct a template for the sum or difference of two cubes.
a^3+b^3 OR a^3-b^3

Step​ 2:  
​(__)^3​+(__)^3 or ​(___)^3​-(___)^3 Fill in the appropriate bases.
Step​ 3: Use this pattern to construct the templates
(a^3+b^3)=(a+b)(a^2-ab+b^2) OR (a^3-b^3)=(a-b)(a^2+ab+b^2)
   a+b a^2-ab+b^2 OR a-b a^2+ab+b^2

Step​ 4:(_______)(__________) or (_____​)(_____​)Insert the bases in the template.
Step​ 5: Write the factors of x^3-8=

1. The cube of the sum formula is                 %28a+%2B+b%29%5E3+=+a%5E3+%2B+3a%5E2%2Ab+%2B+3a%2Ab%5E2+%2B+b%5E3.
      For details and examples of applications of this formula see the lesson The cube of the sum formula in this site.


2. The cube of the difference formula is     %28a+-+b%29%5E3+=+a%5E3+-+3a%5E2%2Ab+%2B+3a%2Ab%5E2+-+b%5E3.
      For details and examples of applications of this formula see the lesson The cube of the difference formula in this site.


3. The sum of cubes formula is                       a%5E3+%2B+b%5E3+=+%28a+%2B+b%29%2A%28a%5E2+-+ab+%2B+b%5E2%29.
