Step-by-step explanation:

Answer:

The factored form of the given expression is (z-6)(z+3).

Step-by-step explanation:

The given expression is

[tex]z^2-3z-18[/tex]

The middle term can by written a -6z+3z.

[tex]z^2-6z+3z-18[/tex]

[tex]z(z-6)+3(z-6)[/tex]

[tex](z-6)(z+3)[/tex]

Therefore the factored form of the given expression is (z-6)(z+3).
