Answer 1

$\huge\boxed{\texttt{\fcolorbox{red}{aqua}{SoLuTiOn :-}}}$

$= > {(2x + 3y)}^{2} - {(2x - 3y)}^{2} \\ = > 4 {x}^{2} + 9 {y}^{2} + 12xy - (4 {x}^{2} + 9 {y}^{2} - 12xy) \\ = > {\cancel{4 {x}^{2}}} + {\cancel{9 {y}^{2}}} + 12xy - {\cancel{4 {x}^{2}}} - {\cancel{9y {}^{2}}} + 12xy \\ = > 24xy$
