Find all the values of \(x\)
at which the following expression attains negative value.
\[
2 x^{2} - 7x - 4
\]
\(x\in \left (-\frac{1}{2};4 \right )\)
\(x\in \left (-\infty ;-\frac{1}{2} \right )\cup \left (4;\infty \right )\)
\(x\in \left( -4;\frac{1}{2}\right) \)
\(x\in \left (-\infty ;-4\right )\cup \left (\frac{1}{2};\infty \right )\)
\(x\in \left( -4;-\frac{1}{2}\right) \)
