$(5x + 3y)² - (5x - 3y)²$

$\large\boxed{\blue{Respuesta}}$

$60xy$

$\large\boxed{\red{solución}}$

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

$25x^{2}+30xy+9y^{2}-\left(5x-3y\right)^{2}$

$25x^{2}+30xy+9y^{2}-\left(25x^{2}-30xy+9y^{2}\right)$

$25x^{2}+30xy+9y^{2}-25x^{2}+30xy-9y^{2}$

$30xy+9y^{2}+30xy-9y^{2}$

$60xy+9y^{2}-9y^{2}$

$\large\boxed{\green{60xy }}$
