Question

plz someone solve this problem​

Answer 1

HEY DUDE STEPWISE EXPLANATION IS HERE ..

$x + \frac{1}{x} = 1$

${x}^{2} - x + 1 = 0$

$so \\ x = - w \\ or \\ x = - {w}^{2}$

NOW PUT THAT ANY VALUE IN GIVEN eqⁿ

U WILL FIND THAT ALL TEARS ARE CANCEL OUT

$- {w}^{2} + {w}^{2} - {w}^{2} + {w}^{2} - {w}^{2} + {w}^{2}$

= 0

So Option A is right answer...

HOPE IT HELPS..
