ᏕᎾᏝᏬᎿᎨᎾᏁ

16m²-(3n+2y)²

= 16m²- 9n²+12my+4y²

Answer 2

Step-by-step explanation:

$\bf \: \underline{ Given-}$

$\textsf{16m² - (3n + 2y)²}$

$\textsf{Using bionomial theorem (a+b)² = a² + 2ab + b² expand (3n + 2y)²}$

$\textsf{16m² - (9n² + 12ny + 4y²}$

$\textsf{To find the opposite of 9n² + 12ny + 4y², find the opposite of each term}$

$\textsf{16m² - 9n² - 12ny - 4y²}$

$\textsf{-(2y + 3n)² + 16m²}$
