What are Polynomial?

Polynomials can have constants, variables and exponents, but never division by a variable.

Therefore, polynomials have constant, variables, exponents that are usually combined with multiplications, addition, subtraction and division.

Hence, the polynomials are as follows:

  • x² - 4
  • - 4 / 7
  • x² - 4 + 7x

The option that is not a polynomials is as follows;

  • 4 / x + x / 7
