Řešení rovnice v reálných číslech
Řeš v \( \mathbb{R} \) rovnici:
\( \large \sqrt {x + 1} + {x^2}-2x-1 = 0 \)
\( \large K = \left \{ 1;\Large \frac{2+\sqrt {5}}{2}\large \right \} \)
\( \large K = \left \{ 0;\Large \frac{1+\sqrt {5}}{2}\large \right \} \)
\( \large K = \left \{ 0;\Large \frac{1-\sqrt {5}}{2}\large \right \} \)
\( \large K = \left \{ -1;\Large \frac{1+\sqrt {5}}{3}\large \right \} \)
