$\tt\blue{If:-}$

$x = \frac{1}{2 \sqrt{7} }$

$\tt\blue{Then:-}$

${x}^{2} + \frac{x}{2 \sqrt{7} } + 1$

${( \frac{1}{2 \sqrt{7} } )}^{2} + (\frac{1}{2 \sqrt{7} } \div 2 \sqrt{7} ) + 1$

$\frac{1}{4 \times7 } + \frac{1}{2 \sqrt{7} \times 2\sqrt{7} } + 1$

$\frac{1}{28} + \frac{1}{28} + 1$

$\frac{2}{28} + 1$

$\frac{1}{14} + 1$

$1 \frac{1}{14}$
