Which algebraic expression is a polynomial?

B.

Step-by-step explanation:

For an algebraic expression to be a polynomial it must have:

1)Variable

2)Constants

3) Exponents of variables which has to be whole number.

These can be combined by math operations except by division of variable

A.

Not a polynomial the last term is a division by variable. This disqualifies it to be a polynomial.

B.

It is a polynomial as it has variables with positive exponents and a constant term.

C.

Not a polynomial the last term[ ] has a variable with exponent which is not a whole number. This disqualifies it to be a polynomial.

D.

Not a polynomial the last term is a division by variable. This disqualifies it to be a polynomial.
