$\n \n 2\sin ^( 2 ){ x } -\sin { x } +2-2=0\n \n 2\sin ^( 2 ){ x } -\sin { x } =0\n \n \sin { x } \left( 2\sin { x } -1 \right) =0$

$\therefore \quad \sin { x } =0\n \n \therefore \quad x=0,\quad \pi ,\quad 2\pi$

$\therefore \quad 2\sin { x } -1=0\n \n 2\sin { x } =1\n \n \sin { x } =\frac { 1 }{ 2 } \n \n \therefore \quad x=\frac { \pi }{ 6 } ,\quad \frac { 5\pi }{ 6 }$
