6.1 The x-intercepts, roots, or
zeroes, are the points in
which the quadratic
crosses the x-axis
6.2 The easiest way to find the
x-intercepts is to graph the
parabola, but using the
factored form equation
(x-+h)(x-+k), h and k would be
the x-intercepts, but with

8.2 The easiest way to do this is to put
your equation into standard form,
(x)=ax^2+bx+c. Then you write in 0
where (x) is, then solve for x. That
gives you the zero of the function
9 Roots of the Equation

10 End Behavior
10.1 The appearance of a graph as
it is followed farther and
farther in either direction. For
polynomials, the end behavior
is indicated by drawing the
positions of the arms of the
graph, which may be pointed
up or down. Other graphs
may also have end behavior
indicated in terms of the
arms, or in terms of
asymptotes or limits.

x-intercepts of a quadratic equation.
Factoring quadratic equations in

accomplished by finding two numbers
that add to give b, and multiply to give
