would it look something like this z*2 - 6 z +8

for future problem like these, use the FOIL method.
Front - multiply the first two numbers in the parenthesis
ex: (y+2) x (y+9)
^ ^
y x y
Outer - multiply the outer numbers
(y+2) x (y+9)
^ ^
y x 9
Inner - multiply the inner numbers
(y+2) x (y+9)
^ ^
+2 x y
Last - multiply the last numbers of the parenthesis
(y+2) x (y+9)
^ ^
+2 x +9
I hope this helps! its super easy if you can just remember this acronym!
