\[x^{2} + (y - 2)^{2} = 5;\ \ \ y = x^{2} - 1.\]
\[x^{2} + \left( x^{2} - 3 \right)^{2} = 5\]
\[x^{2} + x^{4} - 6x^{2} + 9 - 5 = 0\]
\[x^{4} - 5x^{2} + 4 = 0\]
\[Пусть\ x^{2} = t \geq 0:\]
\[t^{2} - 5t + 4 = 0\]
\[t_{1} + t_{2} = 5;\ \ \ t_{1} \cdot t_{2} = 4\]
\[t_{1} = 4;\ \ \ \ t_{2} = 1.\]
\[1)\ x^{2} = 4\]
\[x = \pm 2.\]
\[y = 4 - 1 = 3.\]
\[2)\ x^{2} = 1\]
\[x = \pm 1.\]
\[y = 1 - 1 = 0.\]
\[Ответ:(2;3);( - 2;3);(1;0);\]
\[( - 1;0).\]
