−5p2−4p+7

Answer 1

To add the polynomial expressions \( 3 - 2p - 5p^2 \) and \( p^4 - 3p + 4 \), we will combine like terms.

1. Write down both expressions:
\[
(3 - 2p - 5p^2) + (p^4 - 3p + 4)
\]

2. Combine the constant terms:
\[
3 + 4 = 7
\]

3. Combine the \( p \) terms:
\[
-2p - 3p = -5p
\]

4. The \( p^2 \) term remains:
\[
-5p^2
\]

5. The \( p^4 \) term is simply:
\[
p^4
\]

Now, putting it all together, we have:
\[
p^4 - 5p^2 - 5p + 7
\]

Thus, the final result of the addition is:
\[
\boxed{p^4 - 5p^2 - 5p + 7}
\]
