Are these polynomials?

Algebra Level 2

\[ \large \frac { { x }^{ 2 }+{ y }^{ 2 }+{ z }^{ 2 }-yz-zx-xy }{ { a }^{ 2 }+{ b }^{ 2 }+{ c }^{ 2 }-bc-ca-ab }\]

If \(x=b+c, y=c+a, z=a+b\), then find the value of the expression.

Hint: See how you can use the identity of \({ \left( a-b \right) }^{ 2 }\).
