Dear Student,

\frac{\sqrt{7} - 2}{\sqrt{7} + 2} - \frac{\sqrt{7} + 2}{\sqrt{7} - 2} = \frac{{(\sqrt{7} - 2)}^{2} - {(\sqrt{7} + 2)}^{2}}{(\sqrt{7} - 2) (\sqrt{7} + 2)} = \frac{(7 + 4 - 2 \times \sqrt{7} \times 2) - (7 + 4 + 2 \times \sqrt{7} \times 2)}{7 - 4} . . . . (A s (a - b) (a + b) = a^{2} - b^{2} a n d {(a - b)}^{2} = a^{2} + b^{2} - 2 a b a n d {(a + b)}^{2} = a^{2} + b^{2} + 2 a b) = \frac{11 - 4 \sqrt{7} - 11 - 4 \sqrt{7}}{3} = \frac{- 8 \sqrt{7}}{3}
