8) Number of terms : Monomial

Degree : Constant polynomial

9) Not a polynomial

Step-by-step explanation:

8) Recall that a polynomial with one term is a monomial

A polynomial with a degree of zero is a constant polynomial

Therefore 1 is a monomial, when we classify by number of terms and it is a constant polynomial when we classify by degree since the degree is zero.

9) Note that a polynomial has positive integral indices, therefore   is not a polynomial.

The reason is that, but is not an integer.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

i think the answer would be c
