Answer 2

- then the product is the difference of their squares:

(a + b)(a − b) = a2 − b2

For, the like terms will cancel. (Lesson 16.)

Symmetrically, the difference of two squares can be factored:

x2 − 25 = (x + 5)(x − 5)

x2 is the square of x. 25 is the square of 5.

The sum of two squares -- a2 + b2 -- cannot be factored. See Section 2.
