To add the polynomial expressions \(3 - 2p - 5p^2\) and \(p^4 - 3p + 4\), we can arrange and combine like terms.
-
Write the polynomials: \[ (3 - 2p - 5p^2) + (p^4 - 3p + 4) \]
-
Combine like terms:
- The \(p^4\) term: \(p^4\)
- The \(p^2\) term: \(-5p^2\)
- The \(p\) terms: \(-2p - 3p = -5p\)
- The constant terms: \(3 + 4 = 7\)
-
Write the resulting polynomial with combined terms: \[ p^4 - 5p^2 - 5p + 7 \]
So, the sum of the polynomials \(3 - 2p - 5p^2\) and \(p^4 - 3p + 4\) is: \[ \boxed{p^4 - 5p^2 - 5p + 7} \]
