Question

How to find that this expression is polynomial or not.❌no spam❌​

Answer 1

Step-by-step explanation:

Polynomials must have their powers as natural numbers.

$\frac{1}{x} (x - 1)(x - 2)$

$\frac{1}{x} ( {x}^{2} - 3x + 2)$

$x - 3 + \frac{2}{x}$

$x - 3 + 2 {x}^{ - 1}$

As the power has -1, we can conclude that this isn't a polynomial.
