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^2-5m+1

(Choice C)

-5m^2+4m+3

(Choice D)

3m^2+m-5

Answer 1

D.
`3m^2+m-5`

Explanation:

A trinomial expression is a polynomial expression with three terms.

The term with the highest power of variable is called the leading term and the co-efficient of this term is called the leading co-efficient.

The alone number without any variable in the expression is called the constant.

Example of a trinomial:

`5x^2+2x+4`

Leading co-efficient = 5

Constant = 4

A trinomial with a leading coefficient of 3 and a constant term of -5 from the given choices is:

D.
`3m^2+m-5`
