Overview of shortcut cubic multiplication formulas

This lesson is the overview of the shortcut cubic multiplication formulas.

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

%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 under the current topic 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

%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 under the current topic 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

a%5E3+%2B+b%5E3+=+%28a+%2B+b%29%2A%28a%5E2+-+ab+%2B+b%5E2%29

.
