Using graphs of the functions \(f(x) = x^{2} + x - 1\)
and \(g(x) = -\frac{1}
{2}x\)
solve the following quadratic inequality.
\[
x^{2} + x - 1 > -\frac{1}
{2}x
\]
\(\left (-\infty ;-2\right )\cup \left (\frac{1}
{2};\infty \right )\)
\(\left (-2; \frac{1}
{2}\right )\)
\(\left [ -2; \frac{1}
{2}\right ] \)
\(\left (-\infty ;-2\right ] \cup \left [ \frac{1}
{2};\infty \right )\)
