Answer 2

Answer:

(b) a trinomial

Step-by-step explanation:

Given polynomial 2x - x² + 5

For polynomials, the number of terms is measured by the various exponents of the variable. 2x is twice of "$x^{1}$", -x² is -1 times of "$x^{2}$", and 5 is 5 times of "$x^{0}$" (this is called a constant).

So there are three terms. x², x and constant. This makes this polynomial a trinomial because it has three terms.
