Polynomial:

x^3 - 4x - 3

-x^5 + 7x - 1/2x^2 + 9

x^4 + x^3 √7 + 2x^2 - √3/2x + π

Not a Polynomial:

x^4 + 5/x^3 - √x + 8

[x]^2 + 4√x - 2

4/x^2-4x+3

//hope this helped :)

Polynomial is an expression that consists of indeterminates(variable) and coefficients.

What are polynomial?

Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

As we know about the polynomials, therefore, the expressions that are polynomials are,

Polynomial:

  • [tex]x^3 - 4x - 3[/tex]
  • [tex]-x^5 + 7x - \dfrac{1}{2}x^2 + 9[/tex]
  • [tex]x^4 + x^3 \sqrt7 + 2x^2 - \dfrac{\sqrt3}{2}x + \pi[/tex]

Not a Polynomial:

  • [tex]x^4 + \dfrac{5}{x^3} - \sqrt x + 8[/tex]
  • [tex]x^2 + 4\sqrt x - 2[/tex]
  • [tex]\dfrac{4}{x^2-4x+3}[/tex]
