Question

_______ is not a polynomial in 2 variable.
a》x/2+y/3 =1. b》3x + 5y = 8xy. c》1/x^-1 +1/x^-1=1/5^-1. d》2x +1=3​

Answer 1

a) x/2+y/3=1 is the correct answer

Because x/2 or y/3 is in fraction form..

x/2 can be written as 2x^-1 ....

The degree of a polynomial is a non negative integer

so, x/2+y/2=1 is not a polynomial in two variables

Answer 2

Answer:

$option \: (a) \: \frac{x}{2} + \frac{y}{3} = 1$

$and \: the \: given \: variable \: is \: not \: a \: polynomial$
