Assuming the polynomial is written in terms of "x": It means, what value must "x" have, for the polynomial to evaluate to zero? For example:

f(x) = x2 - 5x + 6

has zeros for x = 2, and x = 3. That means that if you replace each "x" in the polynomial with 2, for example, the polynomial evaluates to zero.

A function maps "input" values to "output" values. A zero of a function is any "input" value that will map to an "output" value of zero. For example, a value of "x" for which the equation f(x) = 0 is true.
