x^2 - 2x - 2\sqrt{2}x + 1 = 0

\[
x^2 - (2 + 2\sqrt{2})x + 1 = 0

\[
x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

\[
D = b^2 - 4ac
\]
\[
D = (-(2 + 2\sqrt{2}))^2 - 4 \cdot 1 \cdot 1

\[
D = (2 + 2\sqrt{2})^2 - 4

\[
D = (4 + 8\sqrt{2} + 8) - 4 = 8 + 8\sqrt{2}

\[
x = \frac{2 + 2\sqrt{2} \pm \sqrt{8 + 8\sqrt{2}}}{2}

\[
x = 1 + \sqrt{2} \pm \frac{\sqrt{8(1 + \sqrt{2})}}{2}
