Add the polynomial expressions 3−2p−5p2 and p4−3p+4.(1 point)

To add the polynomial expressions \(3 - 2p - 5p^2\) and \(p^4 - 3p + 4\), follow these steps:

1. Write the polynomials:

\[
(3 - 2p - 5p^2) + (p^4 - 3p + 4)
\]

2. Group the like terms:

- Constant terms: \(3 + 4 = 7\)
- \(p\) terms: \(-2p - 3p = -5p\)
- \(p^2\) terms: \(-5p^2\)
- \(p^4\) term: \(p^4\)

3. Combine the results:

\[
p^4 - 5p^2 - 5p + 7
\]

Therefore, the answer is:

\[
\boxed{p^4 - 5p^2 - 5p + 7}
\]

This matches the response option:

- \(p^4 - 5p^2 - 5p + 7\)
