Question

Which of the following is a polynomial
$a)x ^{ - 2} + {x}^ { - 1} + 3$
$b)x + x ^{ - 1 } + 2$
$c)x {}^{ - 1}$
$d)0$
Please tell answer for this question ​

Answer 1

Answer:

As we know that degree of the polynomials need to be in whole number.

e.g. - 1 is a constant polynomial

x is a polynomial of degree 1

x^2+x is a polynomial of degree 2

Hence, 0 is a constant polynomial

So, option D is correct...
