Answer 2

Concept

An expression having one variable is known as linear equation in one variable.

Given

Given that

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

Find

We need to find the value of x

Solution

substituting the value of x

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

Hence The value of x = 1
