It says it's a polynomial and that based on the number of terms. So right then you can cancel out cubic and quadratic because they aren't polynomials. Also:
Cubic is just a variable with the exponent of 3. Examples:

Binomial is a polynomial with 2 terms. Examples:

A quadratic has a division sign.
