Question

Which expressions are polynomials??

Answer 1

Options (1) and (2)

Explanation:

Properties of a polynomial,

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

Example:

(y² +
`(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^{(1)/(2)}-1`

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

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