Answer 1

Let's complete the steps as outlined to find the sum based on your equations, focusing on the first one.

1. **Remove the parentheses**.
- Starting expression: \((2x + x + 3) + 134 + (2x + 1) + (x^2 - 2x + 7) + 1 - 2x^2 + 5x - 1\)
- After removing parentheses: \(2x + x + 3 + 134 + 2x + 1 + x^2 - 2x + 7 + 1 - 2x^2 + 5x - 1\)

**Answer after removing parentheses:**
\[
2x + x + 3 + 134 + 2x + 1 + x^2 - 2x + 7 + 1 - 2x^2 + 5x - 1
\]

2. **Collect like terms**.
- Combine terms involving \(x^2\): \(x^2 - 2x^2 = -x^2\)
- Combine terms involving \(x\): \(2x + x + 2x - 2x + 5x = 8x\)
- Combine constant terms: \(3 + 134 + 1 + 7 + 1 - 1 = 145\)

**Answer after collecting like terms:**
\[
-x^2 + 8x + 145
\]

3. **Simplify**.
- Since the expression is simple, we just leave it as it is.

**Final simplified expression:**
\[
-x^2 + 8x + 145
\]

This is the final result of your sum based on the operations provided!
