Which of the following is a trinomial with a constant term?

It should be A

Step-by-step explanation: A trinomial is a polynomial that has three terms. A constant term of a polynomial is a term that doesn't contain variable only number.

A. Polynomial  is a trinomial with a constant term 7.

B. Polynomial  is a trinomial without a constant term.

C. Polynomial  is a binomial (polynomial with two terms).

D. Polynomial  is a monomial (polynomial with one term).

it is A. Polynomial is a trinomial with a constant term 7.

Step-by-step explanation:

answer: what are the following choices

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
