Answer 1

Answer:

the first one is the only polynomial rest all are not polynomial bcz the value will come negative

Answer 2

$\rule{300}{2}$

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R:-}}}}$

Correct answer is (a) because in the polynomial, power or degree of variable x is positive integer whereas in (b) and (c) power of variable x is not integer. And we know that for expression to being a polynomial the power of variable x should be positive integer.

This is the best possible answer
