Question

$\\ \\ 7 \sqrt{2x {}^{2} } - 10x - 4 \sqrt{2}$
find the zero
​

Answer 1

7√2x² - 10x - 4√2

7√2x² - 14x + 4x - 4√2

7√2x(x - √2) +4(x - √2)

(7√2x + 4) (x - √2)

Answer 2

${\orange{\underline{\underline{\bf{\bigstar Solution : }}}}}$

$\\ \\ 7 \sqrt{2x {}^{2} } - 10x - 4 \sqrt{2}$

7 √ 2x² - 10x - 4√2

= 7 × 2x - 10x - 4√2

= 14x - 10x - 4√2

= 4x - 4√2
