Given vectors x=(3,1,−2)\mathbf{x} = (3, 1, -2), y=(−1,2,1)\mathbf{y} = (-1, 2, 1), and z=(2,−1,3)\mathbf{z} = (2, -1, 3), let p=x+ty\mathbf{p} = \mathbf{x} + t\mathbf{y} for some scalar tt. If the angle between p\mathbf{p} and z\mathbf{z} is the same as the angle between x\mathbf{x} and z\mathbf{z}, what are the possible values of tt?
