Flashcard 11 - Mathematics: Algebraic Reasoning Flashcard Set for the TSIA2

A monomial is an expression with one term. A polynomial is an expression of different monomials added to, or subtracted from, each other.

Choice A is a monomial.

Choice C is two monomials multiplied together, resulting in another monomial ($2x^2 \cdot -3x = -6x^3$), not a polynomial.

Choice B consists of three monomials added/subtracted to/from each other. Thus, this is a polynomial.
