Question

7 under root 2 x square - 10 x minus 4 under root 2

Answer 1

$7 \sqrt{2}x {}^{2} - 10x - 4 \sqrt{2} \\ 7 \sqrt{2}x {}^{2} - 14x + 4x - 4 \sqrt{2} \\ 7 \sqrt{2}x(x - \sqrt{2} ) + 4(x - \sqrt{2} ) \\ (7 \sqrt{2}x + 4)(x - \sqrt{2} )$
hope it's help u .....

Answer 2

$7 \sqrt{2} {x}^{2} - 10x - 4 \sqrt{2} \\ 7 \sqrt{2} x {}^{2} - (14 - 4)x - 4 \sqrt{2} \\ 7 \sqrt{2} x {}^{2} - 14x - 4x - 4 \sqrt{2} \\ 7 \sqrt{2}x (x - \sqrt{2} ) + 4(x - \sqrt{2} ) \\ (7 \sqrt{2 } x + 4)(x - \sqrt{2} )$
