1 answer

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

  1. Start with the expression: \[ 3 - 2p - 5p^2 + p^4 - 3p + 4 \]

  2. Now, rearranging and combining like terms:

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

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

Thus, the final answer is: \(p^4 - 5p^2 - 5p + 7\).
