Answer 1

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

1. Start by rewriting both expressions:

   \[ 3 - 2p - 5p^2 \quad (1) \] \[ p^4 - 3p + 4 \quad (2) \]

2. Now, let's align them for addition:

   \[ 0p^4 + 0p^3 - 5p^2 - 2p + 3 \quad (from ; expression ; 1) \] \[ +1p^4 + 0p^3 + 0p^2 - 3p + 4 \quad (from ; expression ; 2) \]

3. Adding these together term by term gives us:

• For \(p^4\): \(0 + 1 = 1\)
• For \(p^3\): \(0 + 0 = 0\)
• For \(p^2\): \(-5 + 0 = -5\)
• For \(p\): \(-2 - 3 = -5\)
• For the constant terms: \(3 + 4 = 7\)

4. So the result of the addition is:

\[ p^4 + 0p^3 - 5p^2 - 5p + 7 \]

5. This simplifies to:

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

So the answer is:

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