Solution = 1 - cubic polynomial with variable "x"

1 - cubic polynomial with variable "x"2- it is not a polynomial because in polynomial there can not be ALGEBRAIC expression in denominator.

1 - cubic polynomial with variable "x"2- it is not a polynomial because in polynomial there can not be algebraic expression in denominator.3- it is a quadratic polynomial having " z" as variable.

1 - cubic polynomial with variable "x"2- it is not a polynomial because in polynomial there can not be algebraic expression in denominator.3- it is a quadratic polynomial having " z" as variable.4- it is also a quadratic polynomial with variable "m ".

1 - cubic polynomial with variable "x"2- it is not a polynomial because in polynomial there can not be algebraic expression in denominator.3- it is a quadratic polynomial having " z" as variable.4- it is also a quadratic polynomial with variable "m ".5- it is not polynomial because polynomial can not have negative exponent .
