Question

Add the polynomial expressions 5 z minus 2 z squared minus 4 z plus 5

Answer 1

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

1. Combine the \(z\) terms:
\[
5z - 4z = 1z \quad \text{(or just \(z\))}
\]

2. The \(z^2\) term remains as:
\[
-2z^2
\]

3. The constant term is:
\[
5
\]

Now, putting it all together, we have:
\[
-2z^2 + z + 5
\]

So, the final result is:
\[
-2z^2 + z + 5
\]
