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

Step-by-step 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)
