Пошаговое объяснение:

$\sqrt{x - 2} = 8 - x$

$x - 2 = 64 - 16x + {x}^{2}$

$x - 2 = 64 + 16x - {x}^{2} = 0$

$17x - 66 - {x}^{2} = 0$

${ - x}^{2} + 17x - 66 = 0$

${x}^{2} - 17x + 66 = 0$

${x}^{2} - 6x - 11x + 66 = 0$

$x(x - 6) - 11(x - 6) = 0$

$(x - 6)(x - 11) = 0$

$x - 6 = 0 \\ x - 11 = 0$

$x = 6 \\ x = 11$

$\sqrt{6 - 2} = 8 - 6 \\ \sqrt{11 - 2} = 8 - 11$

$2 = 2 \\ 3 = - 3$

$x = 6$
