6 answers

well, geez, did you try them?
Or, note that you want (z-9)(z+3) = 0
oh yeah me answer was 3, -9, but that doesn't feel right, or it may just be me
good intuition. You got it exactly backwards.
oh so its -9, 3?
oh wait, -9, 3 isnt an answer,um, is it -3, 9?
now im confused
yeah all of the answers start with either 3 or -3
