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
Varvara68 [4.7K]

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.

2x - 6 : Polynomial

2x^2 -6x+4 : Polynomial

\frac{2}{3}x^4-6x^3+4x : Polynomial

2x^{-2}-6x+4 = \frac{2}{x^2}- 6x + 4 : Not Polynomial because it has a variable in division.

Hope it will help :)
