To find the sum of the given expression \((4pâ2p^2+8)+(5p^2+2p)+(7â3p)\), we first need to combine all the like terms.
Let's break it down step by step:
1. **Grouping Similar Types**:
- Collect all \(p^2\) terms:
\(-2p^2 + 5p^2\)
- Collect all \(p\) terms:
\(4p + 2p - 3p\)
- Collect all constant terms:
\(8 + 7\)
2. **Combining the \(p^2\) Terms**:
- \(-2p^2 + 5p^2 = 3p^2\)
3. **Combining the \(p\) Terms**:
- \(4p + 2p - 3p = 3p\)
4. **Combining the Constant Terms**:
- \(8 + 7 = 15\)
5. **Putting it all Together**:
- Combine the results: \(3p^2 + 3p + 15\)
So, the final sum is:
\[
3p^2 + 3p + 15
\]
Thus, the correct response is:
**3p² + 3p + 15**.
