Problem Statement

Suppose that ω,a,b,c \omega, a,b,c are distinct real numbers for which there exist real numbers x,y,z x,y,z that satisfy the following equations: x\plus{}y\plus{}z\equal{}1, a^2 x\plus{}b^2 y \plus{}c^2 z\equal{}\omega ^2, a^3 x\plus{}b^3 y \plus{}c^3 z\equal{}\omega ^3, a^4 x\plus{}b^4 y \plus{}c^4 z\equal{}\omega ^4. Express ω \omega in terms of a,b,c a,b,c.
