Answer 2

Answer:

Question :-

➠ a² - (2a + 3b)²

Formula used :-

➪ a² - b²

➭ (a + b) (a - b)

Answer :-

➠ a² - (2a + 3b)²

➻ (a)² - (2a + 3b)²

➻ {(a) + (2a + 3b)} {(a) - (2a + 3b)}

➻ (a + 2a + 3b) (a - 2a - 3b)

➻ (3a + 3b) (- a - 3b)

➻ - 3 (a + b) (a + 3b)

∴ The value of a² - (2a + 3b)² is - 3 (a + b) (a + 3b)
