Question

$2 - 5 \sqrt{x}$
​

Answer 1

$2 - 5 \sqrt{x} = 0$

$- 5 \sqrt{x} = 0 - 2$

$5 \sqrt{x} = 2$

$\sqrt{x} = \frac{2}{5}$

${ (\sqrt{x} )}^{2} = { (\frac{2}{5}) }^{2}$

$x = \frac{4}{25}$

Answer 2

Answer:

$2 - 5 \sqrt{x} = 0 \\ = > - 5 \sqrt{x} = 0 - 2 \\ = > \sqrt{x} = \frac{ - 2}{5} \\ = > ({ \sqrt{x} })^{2} = ( { \frac{ - 2}{5} }^{2} ) \\ = > x = \frac{4}{25}$
