P^2-1=0
(p-1)(p+1)=0

Answer:
So we will open the chest with the message: a. If this chest is empty, then the other chest’s message is true.
Step-by-step explanation:
We know that:
a. If this chest is empty, then the other chest’s message is true.
b. This chest is filled with treasure or the other chest contains deadly scorpions.
We know exactly one of these messages is true.
We conclude that the first chest cannot be empty, because then we get that both messages are true.
Since the first chest is not empty, it follows that the message of the second chest is incorrect.
So we will open the chest with the message: a. If this chest is empty, then the other chest’s message is true.
