One of the roots of the equation

x^{2} + p x - 11 = 0

with the parameter

p \in C

is

x_{1} = 3 - i \sqrt{2}

. Find the second root

x_{2}

and the corresponding value of the parameter

p

.

x_{2} = - 3 - i \sqrt{2}, p = 2 i \sqrt{2}

x_{2} = 3 + i \sqrt{2}, p = 6

x_{2} = - 3 - i \sqrt{2}, p = 6

x_{2} = 3 + i \sqrt{2}, p = - 2 i

x_{2} = - 3 - i \sqrt{2}, p = - 2 i \sqrt{2}
