Three vectors x, y and z satisfy x + y + z = 0. Calculate the value of(adsbygoogle = window.adsbygoogle || []).push({});

(x dot y) + (x dot z) + (y dot z) if the magnitude of x is 2, the magnitude of y is 3, and the magnitude of z is 4.

Sorry I don't have time to format this properly, I've got to run off to work. This question has been bugging me, and any help would be greatly appreciated.
