[tex]Answer: \\ (x - 8)(x + 9) = 0 \\ \Leftrightarrow x = 8 \: \vee \: x = - 9 \\ \Rightarrow ( - 9,0)[/tex]

For this case we want to know the x-intercept points of the following quadratic function:

The interdection points of the parabola with the x axis are obtained by making [tex]y = 0[/tex].

[tex]f (x) = (x-8) (x + 9)[/tex]

We have:

[tex]x-8 = 0\\x = 8[/tex]

First point:

(8,0)

So we have:

[tex]x + 9 = 0\\x = -9[/tex]

Second point:

(-9,0)
