Answer 1

To add the polynomial expressions \( 3 - 2p - 5p^2 \) and \( p^4 - 3p + 4 \), we first align the terms by their degrees:

1. Write down the polynomials:

   • First polynomial: \( 3 - 2p - 5p^2 \)
   • Second polynomial: \( p^4 - 3p + 4 \)

2. Rearrange them for addition: \[ -5p^2 - 2p + 3 \] \[

   • p^4 - 3p + 4 \]

3. Now add them by combining like terms:

   • The \( p^4 \) term: \( 1p^4 \)
   • The \( p^2 \) term: \( -5p^2 \)
   • The \( p \) terms: \( -2p - 3p = -5p \)
   • The constant terms: \( 3 + 4 = 7 \)

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

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