Answer 1

To simplify the expression \((8x^3 + 3x^2 - 8x + 10) - (7 + 5x^2 + 5x^3)\), we'll follow these steps:

1. Distribute the negative sign to the terms in the second set of parentheses:
\[
(8x^3 + 3x^2 - 8x + 10) - 7 - 5x^2 - 5x^3
\]

2. Combine like terms:
- For \(x^3\) terms: \(8x^3 - 5x^3 = 3x^3\)
- For \(x^2\) terms: \(3x^2 - 5x^2 = -2x^2\)
- For \(x\) terms: \(-8x - 5x = -13x\)
- For constant terms: \(10 - 7 = 3\)

Thus, combining these results, we have:
\[
3x^3 - 2x^2 - 13x + 3
\]

The correct answer is:
\(3x^3 - 2x^2 - 13x + 3\).
