Answer 1

Answer:

• given (2a-3b)(2a+3b)(4a+9b)

Step-by-step explanation:

1. $( {4a}^{2} - {9b}^{2} )$
2. when we solve two equation (2a-3b)(2a+3b)
3. $( {4a}^{2} - {9b}^{2} )(4a - 9b)$
4. $( 16 {a}^{3} - 81 {b}^{3} )$
5. when we multiplied last two equation.
6. then answar is
7. $16 {a}^{3} - 81 {b}^{3}$
8. Done

Answer 2

Answer:

Question :-

➪ (2a - 3b) (2a + 3b) (4a + 9b)

Answer :-

➪ (2a - 3b) (2a + 3b) (4a + 9b)

➻ 2a(2a + 3b) - 3b(2a + 3b) (4a + 9b)

➻ 4a² + 6ab - 6ab - 9b² × (4a + 9b)

➻ 4a² - 9b² × (4a + 9b)

➻ 4a²(4a + 9b) - 9b²(4a + 9b)

➻ 16a³ + 36a²b - 36ab² - 81b³

∴ The value of (2a - 3b) (2a + 3b) (4a + 9b) is 16a³ + 36a²b - 36ab² - 81b³
