Question

is x^2+1/x a polynomial? give reason for your answer

Answer 1

Answer:

No

Step-by-step explanation:

${x}^{2} + \frac{1}{x}$

Is not a polynomial as in a polynomial variable has the power of any non-negative integer

But in this case, x has the power of -1

As this expression can be written as-

${x}^{2} + \frac{1}{x} \\ \\ = > {x}^{2} + {x}^{ - 1}$

Therefore, this expression is not a polynomial.
