Question

answer this
$(4xy + 3y )^{2} \: \: - (4xy - 3 ) ^{2} \: = 48xy ^{2}$
​

Answer 1

$(4xy + 3y) {}^{2} - (4xy - 3y) {}^{2} \\ \\ = 16 {x}^{2} {y}^{2} + 9y {}^{2} + 24x {y}^{2} - \\ (16 {x}^{2} {y}^{2} + 9y {}^{2} - 24x {y}^{2} ) \\ \\ = 16 {x}^{2} {y}^{2} + 9 {y}^{2} + 24x {y}^{2} - \\ 16 {x}^{2} {y}^{2} - 9 {y}^{2} + 24x {y}^{2} \\ \\ = 48x {y}^{2}$
