Add the polynomial expressions 5z−2z^2−4z+5
and 6z^2+3−7z
To add the polynomial expressions, we add the like terms together:
(5z - 2z^2 - 4z + 5) + (6z^2 + 3 - 7z)
First, let's combine the like terms with z^2: -2z^2 + 6z^2 = 4z^2
Next, we combine the like terms with z: 5z - 4z - 7z = -6z
Finally, we combine the constant terms: 5 + 3 = 8
Putting it all together, the sum of the polynomial expressions is:
4z^2 - 6z + 8.
