Hence proved \frac{1}{1+2w}+\frac{1}{2+w}-\frac{1}{1+w}=0

Step-by-step explanation:

To prove : Expression \frac{1}{1+2w}+\frac{1}{2+w}-\frac{1}{1+w}=0

Proof :

Taking LHS,

LHS=\frac{1}{1+2w}+\frac{1}{2+w}-\frac{1}{1+w}

LHS=\frac{1}{1+2w}+\frac{1+w-2-w}{(2+w)(1+w)}

LHS=\frac{1}{1+2w}+\frac{-1}{2+2w+w+w^2}

LHS=\frac{1}{1+2w}+\frac{-1}{1+2w+1+w+w^2}

As (w denotes Omega/cube root of unity)​ so 1+w+w^2=0

LHS=\frac{1}{1+2w}-\frac{1}{1+2w}

LHS=\frac{1-1}{1+2w}

LHS=0

LHS=RHS

Hence proved.
