Answer 1

Correct Question :-

• (2a + b)³ - (2a - b)³

Solution :-

• → (2a + b)³ - (2a - b)³

Apply identity

• a³ - b³ = (a - b)(a² + ab + b²)

• → 2a + b = a
• → 2a - b = b

According to question

• → [(2a + b) - (2a - b)][(2a + b)² + (2a + b)(2a - b) + (2a - b)²]

Apply identity

• (a + b)² = a² + b² + 2ab
• (a - b)² = a² + b² - 2ab
• a² - b² = (a + b)(a - b)

• → [2a + b - 2a + b][4a² + b² + 4ab + 4a² - b² + 4a² + b² - 4ab]

• → 2b[4a² + 4a² + 4a² + b² - b² + b² + 4ab - 4ab]

• → 2b[12a² + b²]

• → 24a²b + 2b³
