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

p4−5p2−5p+7

To add the polynomial expressions 3 - 2p - 5p^2 and p^4 - 3p + 4, we group the terms with the same powers of p together and then combine like terms:

The powers of p^4, p^2, and p are not present in 3 - 2p - 5p^2. So, these terms remain the same:

p^4 - 5p^2 - 5p

Now, let's combine the constant terms:

3 + 4 = 7

Therefore, the sum of the polynomial expressions is p^4 - 5p^2 - 5p + 7.
