\[ -\frac{1}{2}(\frac{1}{2}-8) + (\frac{1}{2}+3)^2 \]
\[ \frac{1}{2}-8 = \frac{1}{2}-\frac{16}{2} = -\frac{15}{2} \]
\[ \frac{1}{2}+3 = \frac{1}{2}+\frac{6}{2} = \frac{7}{2} \]
\[ -\frac{1}{2}(-\frac{15}{2}) + (\frac{7}{2})^2 \]
\[ -\frac{1}{2} \cdot (-\frac{15}{2}) = \frac{15}{4} \]
\[ (\frac{7}{2})^2 = \frac{49}{4} \]
\[ \frac{15}{4} + \frac{49}{4} = \frac{64}{4} = 16 \]
