√1 is the answer

Answer 2

Answer:

$x = 11 - 6\sqrt{2}$

Step-by-step explanation:

Given that, $\sqrt{2} + \sqrt{x} = 3$

$=>\sqrt{x} = 3 - \sqrt{2}$  [rearranging]

$=>x = (3 - \sqrt{2})^2$  [both sides squared]

$=>x = 3^2 - 2.3.\sqrt{2} + 2$  [using the identity $(a - b)^2 = a^2 - 2.a.b + b^2$]

$=>x = 9 - 6\sqrt{2} + 2 = 11 - 6\sqrt{2}$
