| Difference of squares factors are: (^ means to the power e.g. ^2 means to the power of 2) a^2 - b^2 | (a-b)(a+b) Detail: a^2 +ab -ab -b^2 The positive and negative ab sum to zero leaving a^2 - b^2 |
| Sum of Cubes factors are: a^3 + b^3 | can be factored into (a + b)(a^2 – ab + b^2) |
| Difference of Cubes factors are: a^3 – b^3 | can be factored into (a – b)(a^2 + ab + b^2) |
