Remember from your translation skills that a "difference" means a "subtraction". So a difference of squares is something that looks like x 2 – 4 . That's because 4 = 2 2 , so we really have x 2 – 2 2 , which is a difference of squares.... The sum of any two terms multiplied by the difference of the same two terms is easy to find and even easier to work out — the result is simply the square of the two terms. The middle term just disappears because a term and its opposite are always in the middle.

**Polynomials â€“ Sum and Difference of Two Cubes â€“ Learning**

These sum- and difference-of-cubes formulas' quadratic terms do not have that "2", and thus cannot factor. When you're given a pair of cubes to factor, carefully apply the appropriate rule. By "carefully", I mean "using parentheses to keep track of everything, especially the negative signs".... How to Factor a Sum or Difference of Squares. This is more easily explained using examples but there are some “lyrics to help you remember how to factor a sum or difference of cubes:

**1.6 Factoring Polynomials Mathematics LibreTexts**

The rule for factoring the sum of two perfect cubes is almost the same as the rule for factoring the difference between perfect cubes. You just have to change two little signs to make it work.... A polynomial in the form a 3 + b 3 is called a sum of cubes. A polynomial in the form a 3 – b 3 is called a difference of cubes. Both of these polynomials have similar factored patterns:

- A polynomial in the form a 3 + b 3 is called a sum of cubes. A polynomial in the form a 3 – b 3 is called a difference of cubes. Both of these polynomials have similar factored patterns:
- The same steps can be used for the sum and difference of cubes formula. Review the perfect cubes up to 10. Many times the coefficients will give a clue as to what special binomial formula is to be used.
- The same steps can be used for the sum and difference of cubes formula. Review the perfect cubes up to 10. Many times the coefficients will give a clue as to what special binomial formula is to be used.
- We can use the acronym SOAP to remember the signs when factoring the sum or difference of cubes. The first letter of each word relates to the signs: Same Opposite Always Positive. For example, consider the following example.
