Respuesta :
A trinomial is a polynomial with 3 terms.
but it doen'y include terms whiich have division by a variable.
so these 2 statements disallow B and C
I don't think A is a polynomial
D is the correct choice.

Answer:
D. x^6 - x + √6
Step-by-step explanation:
First let's see what a trinomial is.
A trinomial is a polynomial consists of three terms. The polynomial will not contain the fraction and negative exponents. The exponent/power of variable must be a whole number.
Now let's check out the options.
A. x^3 + x^2 - [tex]\sqrt{x}[/tex]
It has three terms but in the last term we have √x which is x^1/2. Since the exponent is 1/2 it is not a polynomial.
B. 2x^3 - x^2, which has only two terms. This is not a trinomial.
C. 4x^3 + x^2 -1/x, this can be written as 4x^3 + x^2 - x^-1, here the last term's exponent is -1. Therefore, this is not a polynomial.
D. x^6 - x + √6
This is a trinomial.
