What is the difference of squares, and how does if factor?

Correct answer: (a - b) · (a + b) = a² - b²

Step-by-step explanation:

The difference of square we get when we multiply the next two binomials

and applying distributive and commutative law:

(a - b) · (a + b) = a² - ba + ab - b² = a² - ab + ab - b² = a² - b²
