Which expressions are polynomials?

Select each correct answer.

6 + w

2x4−y

z + 1

y2−y√3+4

The expressions that are polynomial are:

6 + w

z + 1

Solution:

polynomial is an expression with variables and coefficients with the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables

1) 6 + w

Here "w" is a variable, hence it is a polynomial expression

This is a polynomial, since it has variables and coefficients and variable with non negative exponent

3) z + 1

This is also a polynomial with variable "z" and has addition operation

Since it has root so it is not a polynomial
