Question

Which is true about the polynomial –8m3 + 11m?

a) It is a binomial with a degree of 2.
b) It is a binomial with a degree of 3.
c) It is a trinomial with a degree of 2.
d) It is a trinomial with a degree of 3.

Answer 1

it is a binomial with degree of 3

Explanation:

Degree is the highest degree of all the terms. Degree of each term can be found by adding the exponent of all the variables .

`-8m^3 +11m`

Here we have 2 terms it is a binomial

-8m^3 have exponent 3 so degree =3

+11m or 11m^1 are same

degree =1

Highest degree is 3

So it is a binomial with degree of 3

Answer 2

b) It is a binomial with a degree of 3.

Explanation:

We need to find about which is true about the polynomial –8m3 + 11m from the given choices.

There are two terms so it is binomial.

Highest exponent on variable m is 3 so degree is 3.

Correct matching choice is "It is a binomial with a degree of 3."

Hence final answer is choice "b) It is a binomial with a degree of 3."
