productos notables ​

Answer 1

Respuesta:

solo se multiplica cada termino

Explicación paso a paso:

( 5m - 3h ) ( -5m - 3h ) =

(5m)(-5m) - (5m)(3h) + (3h)(5m) + (3h)(3h) =

- 25m² - 15mh + 15hm + 9h² =

- 25m² + 9h²

Answer 2

= (5m - 3h)(-5m - 3h)

= 5m(-5m) + 5m(-3h) + (-3h)(-5m) + (-3h)(-3h)

= -5 * 5mm - 5 * 3mh + 3 * 5mh + 3 * 3hh

= -5 * 5mm + 3 *3hh

= -25m² + 9h²
