Answer:
A, C and D are not polynomials
Step-by-step explanation:
A because the variable has a negative power.
C because the variable is in the denominator
D because the variable has a root.
When a variable has a root, it's power is 1/2 which does not count as an ideal polynomial. You might be wondering then that why E is a polynomial?
E is a polynomial because because the root is not on the variable but on the constant.
B and E are polynomials while A,C and D are not.
