Answer:
Option C. is the answer.
Step-by-step explanation:
We have to classify the given expression (5x + 2x² - 8).
This expression has total number of terms = 3
So the expression is a trinomial.
Highest degree term in this expression is 2x², which is a second degree term.
So the expression will be defined as second degree.
In total, the expression is second degree trinomial.
Option C. second degree trinomial is the answer.
