Answer:

C.
(4, 0) and
(-5, 0)

Explanation:

Given the expression,
(x - 4)(x + 5), the x-intercepts would be the values at which the expression = 0.

Rewrite the expression as:


(x - 4)(x + 5) = 0,

Set the first and the second factors equal to 0


(x - 4) = 0


x = 4


(x + 5) = 0


x = -5

All the values that make
(x - 4)(x + 5) = 0 are the x-intercepts of the expression.

x = 4, -5

The point form of the x-intercepts are:


(4, 0) and
(-5, 0)
