To simplify the expression:

\[
8 - 7d + (-8d) - 8d^2 + 2d^2 - 10d
\]

### Step-by-step solution:

1. **Combine like terms for \( d^2 \) terms**:
   - \( -8d^2 + 2d^2 = -6d^2 \)

2. **Combine like terms for \( d \) terms**:
   - \( -7d - 8d - 10d = -25d \)

3. **The constant term** is simply \( 8 \).

### Simplified expression:

\[
8 - 25d - 6d^2
\]

So, the simplified expression is:

\[
-6d^2 - 25d + 8
\]
