Is a polynomial Is not a polynomial

Answer 1

The given expressions are
`(x^(4))/(3)-6,2 x^(4)+12 x+4, x^(3)+4 x \text { and } (3)/(x^(4))-6 x^(3)`.

The polynomial is in the form of
`a x^(2)+b x+c`.

`(x^(4))/(3)-6` in this expression, x is in the numerator. So, it is a polynomial.

`2 x^(4)+12 x+4`, it is a polynomial.

`x^(3)+4 x`, it is a polynomial.

`(3)/(x^(4))-6 x^(3)` in this expression, x is in the denominator. but, x cannot be in the denominator.

So,
`(3)/(x^(4))-6 x^(3)` is not a polynomial.
