Select all of the expressions that would be considered a polynomial

Option B:

Option D:

Solution:

Polynomial definition:

A polynomial can have constants, variables and exponents and fractional coefficient.

A polynomial cannot have fractional exponent, negative exponent and never division by a variable.

To select the expressions that would be considered as a polynomial.

Option A:

√x is not, because the exponent is ½. Fractional exponents are not polynomials.

This is not a polynomial.

Option B:

A polynomial can have constants, variables and exponents.

This is a polynomial.

Option C:

Fractional exponents are not polynomials.

This is not a polynomial.

Option D:

Fractional coefficients are allowed.

This is a polynomial.

Hence and are polynomial.
