What are the x-intercepts for the expression (x-4)(x+5)

C. and

Step-by-step explanation:

Given the expression, , the x-intercepts would be the values at which the expression = 0.

Rewrite the expression as:

,

Set the first and the second factors equal to 0

All the values that make are the x-intercepts of the expression.

x = 4, -5

The point form of the x-intercepts are:

and

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
