choose the correct classification of 5x + 2x2 − 8 by number of terms and by degree.

third degree polynomial

fourth degree trinomial

second degree trinomial

sixth degree polynomial

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.
