Given the expression: 8 x^2 +7x^3-9 a; write the polynomial in descending order. b: classify the polynomial by the number of terms. c: state the degree of the polynomial.

it has degree 3 and it is a trinomial .

Step-by-step explanation:

Since we have given that

A) In descending order:

B) Classify the polynomial by the number of terms:

It is trinomial as it has three terms .

C) Degree of the polynomial :

Since it has highest degree i.e 3

So, the degree of the polynomial is 3.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
