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^−2−6x+4 2/3x^4−6x^3+4x

Respuesta :

Polynomials:
2x−6
2x^2−6x+4
2/3x^4−6x^3+4x

Not Polynomials:
2x^−2−6x+4

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.

[tex] 2x - 6 [/tex] : Polynomial

[tex] 2x^2 -6x+4 [/tex] : Polynomial

[tex] \frac{2}{3}x^4-6x^3+4x [/tex] : Polynomial

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

Hope it will help :)
