\[\sqrt{4x + 5} - \frac{1}{\sqrt{11 - 2x}}\]
\[\left\{ \begin{matrix} 4x + 5 \geq 0\ \ \\ 11 - 2x > 0 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} 4x \geq - 5 \\ 2x < 11\ \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} x \geq - 1\frac{1}{4} \\ x < 5,5\ \ \ \\ \end{matrix} \right.\ \]
\[Ответ:\ \lbrack - 1,25;5,5).\]
