Hello!

The answer is:

-
x-1

-
6+p

-
8x-z^(3)

Why?

A polynomial is a mathematical expression that contains constant values like numbers, and variables like "x, y, z or p", these constants and variables can indicate algebraic operations like addition, subtraction, division, and product. The variables can have exponent numbers that define the degree of a polynomial.

-
x-1 it's a polynomial
because it have a constant value (1) and a variable (x), it's a first degree polymonial.

-
6+p it's a polynomial
because it have a constant value (6) and a variable (p), it's a first degree polynomial.

-
8x-z^(3) it's a polynomial s
ince it have a combination of two variables (x and z), it's a third degree polynomial since the largest exponent is 3.

-
5x^(2) -√(x) is not a polynomial
since it have a square root. Polynomials does not contains roots.

Have a nice day!
