\[z_{1} = x - 8 - 6i;\ \]
\[z_{2} = 2x^{2} + 6i - 2.\]
\[1)\ Действительная\ часть:\]
\[(x - 8) = - \left( 2x^{2} - 2 \right)\]
\[x - 8 = 2 - 2x^{2}\]
\[2x^{2} + x - 10 = 0\]
\[D = 1 + 80 = 81\]
\[x_{1} = \frac{- 1 - 9}{2 \bullet 2} = - 2,5;\ \]
\[x_{2} = \frac{- 1 + 9}{2 \bullet 2} = 2.\]
\[2)\ Мнимая\ часть:\]
\[- 6 = - 6\]
\[x \in R.\]
\[Ответ:\ - 2,5;\ 2.\]
