\[ (4-\frac{3}{8})^2 + (2-\frac{3}{8})(2+\frac{3}{8}) \]
\[ (4-\frac{3}{8})^2 = (\frac{32}{8}-\frac{3}{8})^2 = (\frac{29}{8})^2 = \frac{841}{64} \]
\[ (2-\frac{3}{8})(2+\frac{3}{8}) = 2^2 - (\frac{3}{8})^2 = 4 - \frac{9}{64} = \frac{256}{64} - \frac{9}{64} = \frac{247}{64} \]
\[ \frac{841}{64} + \frac{247}{64} = \frac{1088}{64} \]
\[ \frac{1088}{64} = 17 \]
