Factor the trinomial completely. If the polynomial cannot be factored, write "prime."
-$z ^ { 2 } - 10 z + 25$
A) $( z - 5 ) ^ { 2 }$
B)(z - 5)(z + 5)
C)(z - 10)(z + 10)
D) $( z + 5 ) ^ { 2 }$

The trinomial $z^2 - 10z + 25$ can be factored as $(z - 5)^2$ because $(-5) \times (-5) = 25$ and $-5 - 5 = -10$, which matches the middle term and constant term of the trinomial.
