Question
Which of the following expression are polynomials?
$\frac{(\text{x}-2)(\text{x}-4)}{\text{x}}$
$\frac{(\text{x}-2)(\text{x}-4)}{\text{x}}$
✓
Answer
Not Polynomial, because the exponent of the variable of $\frac{(\text{x}-2)(\text{x}-4)}{\text{x}}=\frac{\text{x}^2-6\text{x}+8}{\text{x}}=\text{x}-6+8\text{x}^{-1}$ is -1 which is not whole number.
