Hello!
The answer is:
- [tex]x-1[/tex]
- [tex]6+p[/tex]
- [tex]8x-z^{3}[/tex]
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.
- [tex]x-1[/tex] it's a polynomial because it have a constant value (1) and a variable (x), it's a first degree polymonial.
- [tex]6+p[/tex] it's a polynomial because it have a constant value (6) and a variable (p), it's a first degree polynomial.
- [tex]8x-z^{3}[/tex] it's a polynomial since it have a combination of two variables (x and z), it's a third degree polynomial since the largest exponent is 3.
- [tex]5x^{2} -\sqrt{x}[/tex] is not a polynomial since it have a square root. Polynomials does not contains roots.
Have a nice day!
