$x = \sqrt{5 - 2 \div 5 + 2} = sqare \: cancils \: and \: euation \: be \: like$

Step-by-step explanation:

$5 - 2 \div 5 + 2$

and it will be

Answer 2

Answer:

(9-4√5)/(9+4√5)

Step-by-step explanation:

If

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

Then, x² =;

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

${x}^{2} = \frac{5 + 4 - 4 \sqrt{5} }{5 + 4 + 4 \sqrt{5} }$

${x}^{2} = \frac{9 - 4 \sqrt{5} }{9 + 4 \sqrt{5} }$
