Answer:

You find the zeros of a quadratic functions by factoring the function. And once you have factored the function you take the factors and flip the signs. For example, you have the factors (x-4) and (x+3).

Drop the parentheses and make x equal to zero.

x - 4 = 0                                        x - 3 = 0

Solve it like a one step equation.

x - 4 = 0                        x - 3 = 0

 + 4    +4                         +3    +3

= 4                                    = 3

Then turn into coordinates.

 x y         x y

(4,0)       (3,0)

Note that the zero's are the x-intercepts. I labeled x above the first part of the coordinate to show where the x-intercepts should and the same with the y.
