Answer 2

To simplify the given expression, let's proceed step-by-step:

1. Combine like terms within parentheses: (3a + 2a) = 5a

2. Expand the expression: (5a) • (1 - 6a + 9a²) • (1 - 3a) • (3a + 1) • (b • a² + 10a)

3. Combine like terms again: 1 - 6a + 9a² = (1 - 3a)²

4. Substitute the result back into the expression: (5a) • [(1 - 3a)²] • (1 - 3a) • (3a + 1) • (b • a² + 10a)

5. Expand further: (5a) • (1 - 3a)² • (3a + 1) • (b • a² + 10a)

6. Expand (1 - 3a)²: (1 - 3a)² = (1 - 3a) • (1 - 3a) = 1 - 3a - 3a + 9a² = 1 - 6a + 9a²

7. Substitute the result back into the expression: (5a) • (1 - 6a + 9a²) • (3a + 1) • (b • a² + 10a)

8. Expand further: (5a) • (3a + 1) • (b • a² + 10a)

9. Distribute (5a) across (3a + 1): (5a) • (3a) + (5a) • (1) • (b • a² + 10a)

10. Simplify: 15a² + 5a • (b • a² + 10a)

11. Distribute (5a) across (b • a² + 10a): 15a² + 5a • b • a² + 5a • 10a

12. Simplify further: 15a² + 5ab • a² + 50a²

13. Combine like terms: 15a² + 5ab • a² + 50a² = 65a² + 5ab • a²

So, the simplified expression is: 65a² + 5ab • a²
