Well there is this equation what we call Special products and factoring

wherein it is in terms in x and y


(x+y)(x-y) = x²-y²
it is a special product in which you can use it in a situation like this


using the special product that we know 

(x+3)(x-3)= x² - (3)²

it will take the hassle it expanding it to

(x+3)(x-3) = x² + 3x - 3x - 3(3)
                  =x² + 3²

you can search in google for Special products and Factoring for more Special Products and Factoring.
