Add the polynomial expressions 5z−2z2−4z+5 and 6z2+3−7z.
To add the polynomial expressions, we group the like terms and combine them:
(5z−2z²−4z+5) + (6z²+3−7z)
= 5z − 2z² − 4z + 5 + 6z² + 3 − 7z
= (-2z² + 6z²) + (5z - 4z - 7z) + (5 + 3)
= 4z² - 6z + 8

The following describes a context clue:
A context clue is a piece of information or hint that helps the reader understand the meaning of an unknown word or phrase. It is typically found in the surrounding sentences or paragraph and provides context to help deduce the intended meaning.
To add the polynomial expressions 5z - 2z^2 - 4z + 5 and 6z^2 + 3 - 7z, we combine like terms.
First, let's combine the terms with z^2:
-2z^2 + 6z^2 = 4z^2
Next, let's combine the terms with z:
5z - 4z - 7z = 4z
Finally, let's combine the constant terms:
5 + 3 = 8
Putting it all together, the sum of the polynomial expressions is:
4z^2 + 4z + 8
