Zeros of the function
An input value that produces
an output of 0. If the function
maps real numbers to real
numbers, its 0's are the
x-coordinates of the points
where its graph meets the
x-axis.

Roots of the equation
The roots are exactly
the x-intercepts of the
quadratic function , that
is the intersection
between the graph of
the quadratic function
with the x-axis.

A "quadratic" is a polynomial that looks like "ax2 +
bx + c", where "a", "b", and "c" are just numbers.
For the easy case of factoring, you will find two
numbers that will not only multiply to equal the
constant term "c", but also add up to equal "b", the
coefficient on the x-term.
