Factor the expression below x^2-64

(x + 8) (x-8)

Step-by-step explanation:

x^2-64

Solve

a^2 - b^2 = (a+b) (a-b)

Where a = x , b = 8

(x + 8) (x-8)

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
