(x + 2 )^2 - ( y + 2 )^2 use the difference of two squares identity to you rewrite the expression in factored form. be sure to simplify each factor.

The difference of two squares factoring pattern states that a difference of two squares can be factored as follows:

So, whenever you recognize the two terms of a subtraction to be two squares, you can factor it as the sum of the roots multiplied by the difference of the roots.

In this case, the squares are obvious: is the square of , and is the square of

So, we can factor the expression as

(the round parenthesis aren't necessary, I used them only to make clear the two terms)

We can simplify the expression summing like terms:
