Question

please solve this i will surly mark as a branlist and answer it correctly please... urgently​

Answer 1

$\sqrt{8 } - \sqrt{x} = \sqrt{x} - \sqrt{4} \\ 2 \sqrt{x} = \sqrt{8} + \sqrt{4} \\ 4x = {( \sqrt{8} + \sqrt{4} )}^{2} \\ 4x = 8 + 4 +( 2 \times \sqrt{8} \times \sqrt{4} ) \\ 4x = 12 + (2 \times 4 \sqrt{2} ) \\ x = 3 + 2 \sqrt{2}$

Answer 2

Answer:

x = 3 + 2√2 is the correct answer.
