Answer:
Step-by-step explanation:
Definition : The expression that can have constants (like 4), variables (like x or y) and exponents (like the 2 in 
), that can be combined using addition, subtraction, multiplication and division, but no division by a variable and a variable's exponents can only be 0,1,2,3,... etc. and it can't have an infinite number of terms.
1. 6 + p
Being p be a variable this equation is polynomial
2. x – 1
Since x-1 has variable and constant so according to definition it is a polynomial
3. 8x−z3
According to definition it is a polynomial
4 .
Since has root so it is not a polynomial .
