 It seems the only values that make the equation true are x=y=z=(1 or -1), then the answer is 3.

Prachi from Beverly Hills, CA 90210 (?) sent me a message to explain my answer step by step so here it is.
If x=1 and y=1 and z=1 based on the only possible values that solve the given equation,
then  x^2+y^2+z^2= 1^2 + 1^2 + 1^2 = 1 + 1 + 1 = 3.
MY QUESTION TO PRACHI IS WHERE DO YOU REALLY LIVE?
