FRONT: Which expression is a polynomial? $$3x^2+5x-7$$ $$\bf{or}$$ $$2x-\dfrac{3x^2}{2x}+6$$

Flashcard 1 - High School Algebra I Flashcard Set for the STAAR test

\[3x^2+5x-7\]

$2x-\dfrac{3x^2}{2x}+6$ is not a polynomial

since the term $\dfrac{3x^2}{2x}$ in this expression is undefined when $x = 0$.
