\({\left( {x - 2} \right)^2} + {\left( {y + 1} \right)^2} = 4\)

\({\left( {x - 2} \right)^2} + {\left( {y - 1} \right)^2} = 4\)

\({(x - 1)^2} + {(y - 2)^2} = 4\)

\({(x - 1)^2} + {(y + 2)^2} = 4\)

\(\overline z = - 3 - i\)

\(\overline z = 3 + i\)

\(\overline z = - 3 + i\)

\(z = i\left( {3i + 3} \right)\)

\(\min \left| {\rm{w}} \right| = \frac{{2\sqrt {26} }}{{13}}.\)

\(\min \left| {\rm{w}} \right| = \frac{{\sqrt {26} }}{{26}}.\)

\(\min \left| {\rm{w}} \right| = \frac{{\sqrt {13} }}{{13}}.\)

\(\min \left| {\rm{w}} \right| = \frac{{\sqrt {26} }}{{13}}.\)

\(\max \left| w \right| = \sqrt 5 - 1\)

\(\max \left| w \right| = 2\sqrt 5 + 2\)

\(\max \left| w \right| = 3\sqrt 5 + 2\)

\(\max \left| w \right| = 2\sqrt 5 + 1\)

\(M + N = 2\sqrt 5 .\)

\(M + N = 2\sqrt {10} .\)

\(M + N = 4.\)

\(M + N = 3\sqrt 5 .\)

\(\left| z \right| = \frac{{5\sqrt {34} }}{3}\)

\(\left| z \right| = \sqrt {34} \)

\(\left| z \right| = \frac{{\sqrt {34} }}{3}\)

\(\left| z \right| = 34\)

\(4x + 2y - 1 = 0\)

\(4x - 2y - 1 = 0\)

\(4x - 2y + 1 = 0\)

\(4x - 6y - 1 = 0\)

\(\frac{{16}}{{15}} - \frac{{11}}{{15}}i\)

\(\frac{9}{5} - \frac{4}{5}i\)

\(\frac{9}{{25}} - \frac{{23}}{{25}}i\)
