Respuesta :
The expressions that are polynomial are:
6 + w
[tex]2x^4 - y[/tex]
z + 1
Solution:
A 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
[tex]2)\ 2x^4 - y[/tex]
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
[tex]4)\ y^2 - y\sqrt{3} + 4[/tex]
Since it has root so it is not a polynomial
