Is each expression a polynomial?

drag and drop each expression to the correct box.

is a polynomial is not a polynomial

(2x - 6)
(2x^2 - 6x - 4)
(2x^-2 - 6х + 4)
(2/3x^4 — 6х + 4х)

Polynomials:

2x−6

2x^2−6x+4

2/3x^4−6x^3+4x

Not Polynomials:

2x^−2−6x+4

Step-by-step explanation:

Alright , lets get started.

A polynomial can have constants, variables or exponents that can be combined using addition, subtraction, multiplication and division but not division by a variable.
