Question

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.

Answer 1

Answer: it has degree 3 and it is a trinomial .

Explanation:

Since we have given that

`8x^2+7x^3-9`

A) In descending order:

`7x^3+8x^2-9`

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.

Answer 2

Answer: A. 7x^3+8x^2-9 , B. The number of terms= 3, C. The degree of the polynomial= 3.

Explanation:

Given that,

8x^2+7x^3-9

A. To write the polynomial in descending order.

We need to put the higher order term with sign first then lower order term.

So,

The polynomial in descending order, 7x^3+8x^2-9

B. The terms are separated by the sign of plus or minus.

So,

The number of terms in the given polynomial = 3

C. The degree of a polynomial is the highest power of individual terms in the polynomial.

So,

The degree of polynomial = 3
