Given : x =  \frac{1}{2 \sqrt{7} }

Now,

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

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

                                      =  (\frac{1}{2 \sqrt{7} } )^2

                                      =  \frac{1}{28}


x^2 -  \frac{x}{2 \sqrt{7} } + 1 = ( \frac{1}{2 \sqrt{7} } )^2 -  \frac{1}{28} + 1

                                                    =  \frac{1}{28} -  \frac{1}{28} + 1

                                                    = 1



Hope this helps!
