a) c^ + 2/c - 3
b)6/x + 2y
c)3/4x - 2y
I've read somewhere that a variable under the division bar, which is in the denominator, can not be a polynomial. I even don't know why. Help?
What about the letter c question, the variable "x" is located parallel to the division bar which is between the numerator and denominator. Is that still a polyomial?

Please read my statements after the question well.

CORRECTION!
Letter a is:
c^2 + 2/c - 3

a b and c are not polynomials

All of these are non-polynomials
The reason is: What if the value of the variable is 0?
Then its Math Error, because nething divided by 0 is Undefined!
In question (c) assume the value of x = 0 then its 3/0 - 2y
which is undefined - 2y Hence, u still wont get ur result.
Hope that helps!

From my geometry and algebra classes, a polynomial is an expression with three or more terms (seperated by a plus, minus, divide, or multiply). So A is a polynomial, B is not (it's a binomial) and C is also a binomial.
I really hope that helped!

Actually, that's true. When a variable is under the division bar, it is now what we call a "rational algebraic expression."

(3/4)x - 2y is a polynomial.
