what is the answer of this​

Answer 1

$\huge \red{ \underline{ \underline{QUESTION \: - }}}$

$\large {= > { (2x \: - \frac{1}{2x}) }^ {2} - (2x - \frac{1}{2x} )(2x + \frac{1}{2x} )}$

$\huge \pink{ \underline{ \underline{SOLUTION \: - }}}$

$\large {= > { (2x \: - \frac{1}{2x}) }^ {2} - (2x - \frac{1}{2x} )(2x + \frac{1}{2x} )} \:$

TAKING COMMON :-

$\large { = > (2x - \frac{1}{2x} ) \{2x - \frac{1}{2x} - 2x \: - \frac{1}{2x} \}}$

$\large {= > (2x - \frac{1}{2x}) ( \frac{ - 1}{2x} - \frac{ 1}{2x} )}$

$\large {= > (2x - \frac{1}{2x}) ( \frac{ 2}{2x} )}$

$\large {= > (2x \times \frac{1}{x} ) - ( \frac{1}{2x} \times \frac{1}{x} )}$

$\large {= > 2 - \frac{1}{2 {x}^{2} } } \\ </p><p> \\ \large {= > \frac{4 {x}^{2} - 1 }{2 {x}^{2} }}$
