Answer 2

Answer:

$( \frac{5}{2x} - \frac{y}{3} )( \frac{5}{2x} + \frac{y}{3} )$

Step-by-step explanation:

$\frac{25}{4 {x}^{2} } - \frac{ {y}^{2} }{9} \\ = ) (\frac{5}{2x} {)}^{2} - ( \frac{y}{3} {)}^{2} \\ {a}^{2} - {b}^{2} = (a - b)(a + b) \\ = ) (\frac{5x}{2x} - \frac{y}{3} )( \frac{5x}{2x} + \frac{y}{3)}$
