Question

Which expressions are polynomials??

Answer 1

Answer:

Options (1) and (2)

Step-by-step explanation:

Properties of a polynomial,

1). A polynomial having division by a variable can't be defined as a polynomial.

  Example:

   (y² + $\frac{x}{1+x}$)

2). A polynomial can't have a negative exponent.

  Example : $(x^{-2}+y-6)$

3). Polynomials don't have the radicals.

  Example : y² + x√3

4). A polynomial can't have a fraction exponent.

   Example : $x^2+x^{\frac{1}{2}}-1$

By these properties, Options (3) and (4) are not the polynomials.

Options (1) and (2) are the correct options.
