\[D = ( - 9)^{2} - 4 \cdot 1 \cdot ( - 22) =\]
\[= 81 + 88 = 169\]
\[x_{1} = \frac{9 + \sqrt{169}}{2 \cdot 1} = \frac{9 + 13}{2} =\]
\[= \frac{22}{2} = 11\]
\[x_{2} = \frac{9 - \sqrt{169}}{2 \cdot 1} = \frac{9 - \ 13}{2} =\]
\[= - \frac{4}{2} = - 2\]
\[D = ( - 5)^{2} - 4 \cdot 1 \cdot ( - 14) =\]
\[= 25 + 56 = 81\]
\[x_{1} = \frac{5 + \sqrt{81}}{2 \cdot 1} = \frac{5 + 9}{2} = \frac{14}{2} = 7\]
\[x_{2} = \frac{5 - \sqrt{81}}{2 \cdot 1} = \frac{5 - 9}{2} =\]
\[= - \frac{4}{2} = - 2\]
\[Ответ:\ x = - 2.\]
