Determine if the expression -8c-9c^4d^2−8c−9c 4
d
2
is a polynomial or not. If it is a polynomial, state the type and degree of the polynomial.

anyone know?

is a polynomial of type binomial and has a degree 6.

Step-by-step explanation:

Given the polynomial expression

Group like terms

Add similar elements: -8c-8c-9c=-25c

Thus, the polynomial is in two variables and contains two, unlike terms. Therefore, it is a 'binomial' with two, unlike terms.

Each term has a degree equal to the sum of the exponents on the variables.

The degree of the polynomial is the greatest of those.

25c has a degree 1

has a degree 6.   (adding the exponents of two variables 'c' and 'd').

Thus,

is a polynomial of type binomial and has a degree 6.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
