Question

which is true about the polynomial $-8m^3 + 11m$?

• it is a binomial with a degree of 2.
• it is a binomial with a degree of 3.
• it is a trinomial with a degree of 2.
• it is a trinomial with a degree of 3.

Explanation:

Step1: Count polynomial terms

The polynomial $-8m^3 + 11m$ has 2 distinct terms, so it is a binomial.

Step2: Find polynomial degree

The highest exponent of the variable $m$ is 3 (from the term $-8m^3$), so the degree is 3.

Answer:

It is a binomial with a degree of 3.
