z2 - 4

first set up your parenthesis for factoring

( )( )

now put in your "z" in both first places in the parenthesis because this is obviously the only place it can go

(z )(z )

now find what can multiply to 4 and add or subtract to equal 0... the answer is -2 and 2 so put both these numbers in the remaining spots

(z - 2)(z + 2)

this is now in factored form
