Answer 2

Answer:

Question:-

a) (a + 3)² - 9

b) 16 - 25(b + 3)²

c) c² - (d + 2)²

d) (2h - 1)² - 4k²

e) 25m² - (n - 1)²

f) (p + 1)² - (p - 1)²

Formula used :-

➪ a² - b²

➭ (a + b) (a - b)

Solution :-

a) (a + 3)² - 9

➻ (a + 3)² - (3)²

➻ {(a + 3) + (3)} {(a + 3) - (3)}

➻ (a + 3 + 3) (a + 3 - 3)

➻ (a + 6) (a)

➻ a² + 6a

b) 16 - 25(b + 3)²

➻ (4)² - {5(b + 3)}²

➻ {4 - 5(b + 3)} {4 + 5(b + 3)}

➻ (4 - 5b - 15) (4 + 5b + 15)

➻ (4 - 15 - 5b) (4 + 15 + 5b)

➻ (- 11 - 5b) (19 + 5b)

➻ - (11 + 5b) (19 + 5b)

c) c² - (d + 2)²

➻ (c)² - (d + 2)²

➻ (c + d + 2) (c - d + 2)

d) (2h - 1)² - 4k²

➻ (2h - 1)² - (2k)²

➻ (2h - 1 + 2k) (2h - 1 - 2k)

e) 25m² - (n - 1)²

➻ (5m)² - (n - 1)²

➻ (5m + n - 1) (5m - n - 1)

f) (p + 1)² - (p - 1)²

➻ {(p + 1) + (p - 1)} {(p + 1) - (p - 1)}

➻ (p + 1 + p - 1) (p + 1 - p + 1)

➻ (2p) (2)

➻ 4p
