Explanation:
Polynomial: it is of expression in which the exponent of all variable should be whole number.
According to this , the expression which are not polynomial are,
[tex]\begin{gathered} 1)\frac{4}{x}-5\ldots\ldots\ldots\text{.}\mathrm{}\text{ exponent for x is -1} \\ 2)x^{-5}-4x^3+x\ldots\ldots\text{... exponent for x is -}5 \\ 3)4\sqrt[]{x}\ldots\ldots\ldots\ldots\text{.. exponent for x is fraction that is }\frac{1}{2} \\ 5)(x+3)(2x-3)^{-2}\ldots\text{. exponent for x is -}2 \end{gathered}[/tex]
All the above expressions are not polynomial.
