A. 7x^3+8x^2-9 , B. The number of terms= 3, C. The degree of the polynomial= 3.
A. To write the polynomial in descending order.
We need to put the higher order term with sign first then lower order term.
The polynomial in descending order, 7x^3+8x^2-9
B. The terms are separated by the sign of plus or minus.
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.
The degree of polynomial = 3
it has degree 3 and it is a trinomial .
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.
