Question

Determine which expressions are polynomials. Explain your reasoning.

Answer 1

Answer:

B

Step-by-step explanation:

A polynomial is an expression containing two or more algebraic terms. They are often the sum of several terms containing different powers (exponents) of variables and never contains square roots or division by a variable.

In your case, option A contains square root, thus this expression is not a polynomial. Option C contains division by a variable, thus this is not a polynomial too.
