Question

Pick the expression that matches this description:

A trinomial with a leading coefficient of 3 and a constant term of −5

Choose 1 answer:

(Choice A)

3m^2−5

(Choice B)

3m^2+m−5

(Choice C)

−5m^2+4m+3

(Choice D)

3m^2−5m+1

Answer 1

Using concepts of elementary functions an polynomials we can find the correct alternative which is

(Choice B)

3m^2+m−5

Explicação passo-a-passo:

The problem is to find a trinomial with a leading coefficient of 3 and a constant term of −5.

A trinomial function is a polynomial consisting of three terms

The leading coeficiente is the constant which follow the highest degree and the constant term is the constant number alone, without a variable.

With all that said we can see that the correct alternative is

(Choice B)

3m^2+m−5

3 is the leading coeficient, -5 is the constant term and is has 3 terms, 3m^2, m and −5
