Answer 2

Let's simplify the expression step by step:

1. Combine like terms within parentheses:

3a + 3b - a - 3b^2(x - 3.8) - 2x - 14 + x - 42 + 15 + 2x - m - (-2m - 3.7) - 3m

2. Distribute the -3b^2 to the terms inside the parentheses:

3a + 3b - a - 3b^2x + 11.4b^2 - 2x - 14 + x - 42 + 15 + 2x - m + 2m + 3.7 - 3m

3. Combine like terms:

(3a - a) + (3b - 2x + x + 2x) + (-3b^2x - m + 2m - 3m) + (11.4b^2 - 14 - 42 + 15 + 3.7)

4. Simplify further:

2a + 6b - 2x - 2b^2x - m - 24.3

So, the simplified expression is:

2a + 6b - 2x - 2b^2x - m - 24.3
