What are the solutions of x^2 - 4 = 0

It is a difference of squares, so we can factor this to

Then, we can solve for .

Hope this helps.

頑張って!

b is the final answer! : )

(- 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 )
