\frac{8\sqrt{3}}{16}-\frac{\sqrt{2}}{16}+\frac{1}{4}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 2 and 16 is 16. Multiply \frac{\sqrt{3}}{2} times \frac{8}{8}.
\frac{8\sqrt{3}-\sqrt{2}}{16}+\frac{1}{4}
Since \frac{8\sqrt{3}}{16} and \frac{\sqrt{2}}{16} have the same denominator, subtract them by subtracting their numerators.
\frac{8\sqrt{3}-\sqrt{2}}{16}+\frac{4}{16}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 16 and 4 is 16. Multiply \frac{1}{4} times \frac{4}{4}.
\frac{8\sqrt{3}-\sqrt{2}+4}{16}
Since \frac{8\sqrt{3}-\sqrt{2}}{16} and \frac{4}{16} have the same denominator, add them by adding their numerators.
