Answer 2

1. (3m² - p)(m² + p) Simplifying the expression:

   = 3m² * m² + 3m² * p - p * m² - p * p = 3m^4 + 3m²p - p * m² - p²

2. (5a² + b)(b² - 4a²) Simplifying the expression:

   = 5a² * b² - 4a² * b + b * b² - 4a² * b² = 5a²b² - 4a²b + b³ - 4a²b²

3. (12a² - 3)(5a - 7a²) Simplifying the expression:

   = 12a² * 5a - 12a² * 7a² - 3 * 5a + 3 * 7a² = 60a³ - 84a^4 - 15a + 21a²

4. (2a³ - 3a²)(a + 5) Simplifying the expression:

   = 2a³ * a + 2a³ * 5 - 3a² * a - 3a² * 5 = 2a^4 + 10a³ - 3a³ - 15a²
