Answer 2

$formula \: \: used: {(x + y)}^{2} = {x}^{2} + {y}^{2} + 2xy \\ \\ = > ( \frac{2x}{3} + \frac{5}{4} ) ^{2} \\ \\ = > {( \frac{2x}{3} )}^{2} + {( \frac{5}{4} )}^{2} + 2. \frac{2x}{3} . \frac{5}{4} \\ \\ = > \frac{4 {x}^{2} }{9} + \frac{25}{16} + \frac{2x}{ \\ 3} . \frac{5}{2} \\ \\ \boxed{ = > \frac{4 {x}^{2} }{9} + \frac{25}{16} + \frac{5x}{3} }$
