Answer:
Step-by-step explanation:
"4x2 – 3x + StartFraction 2 Over x EndFraction" is definitely not a polynomial because one of the exponents of x is negative.
"–6x3 + x2 – StartRoot 5 EndRoot" is a polynomial because all of the exponents of x are integers 0 or greater.
The presence of any root (fractional exponents included) of the variable x automatically disqualifies such expression: it's not a polynomial.
