Answer 1

Answer:

$\textbf{Given:} \left( \frac{a}{2b} + \frac{2b}{a} \right) \]{}^{2} - \left( \frac{a}{2b} - \frac{2b}{a} \right) \] {}^{2} - 4$

Solv.

$\left( \frac{a}{2b} + \frac{2b}{a} \right) \]{}^{2} - \left( \frac{a}{2b} - \frac{2b}{a} \right) \] {}^{2} - 4 = [ \left( \frac{a}{2b} + \frac{2b}{a} \right) \ + \left( \frac{2b}{a} - \frac{a}{2b} \right) \]] \: [ \left( \frac{a}{2b} + \frac{2b}{a} \right) \] - \left( \frac{2b}{a} - \frac{a}{2b} \right) \] {]}^{} - 4$

$\: \: \: \: \: \: \: \: \: \: [∴ {a}^{2} - {b}^{2} = (a - b)(a + b)]$

$= [ \frac{2b}{a} + \frac{2b}{a} ][ \frac{a}{2b} + \frac{a}{2b} ] - 4$

$= [ \frac{2b + 2b}{a} ] [ \frac{a + a}{2b} ] - 4 = [ \frac{4b}{a} ][ \frac{2a}{2b} ] - 4$

$= \frac{8ab}{2ab} - 4 = 4 - 4 = 0$
