Question

plz guys answer it fast 5no. (ii).​

Answer 1

${2x}^{2} + {y}^{2} + {8z}^{2} - 2\sqrt{2xy} + 4\sqrt{2yz} - 8xz$

$= ( { - \sqrt{2x} })^{2} + {y}^{2} + ({ 2\sqrt{2z} }^{2} ) + 2( - \sqrt{2x} )(y) + 2(y)( 2\sqrt{2z} ) + 2( - \sqrt{2x} )( 2\sqrt{2z} )$

$= ({ - \sqrt{2x } + y + 2\sqrt{2z} })^{2}$

$= ( - \sqrt{2x} + y + 2 \sqrt{2z} )( - \sqrt{2x} + y + 2\sqrt{2z} )$

hope it helps
