Find the x-intercepts for the parabola defined
by this equation:
y=-4x2 - 4x + 8
write your answer as two ordered pairs:
(x1, y1), (x2, y2)
separate the values with a comma. round, if
necessary, to the nearest hundredth.
enter the correct answer,

(- 2, 0 ), (1, 0 )

Step-by-step explanation:

Given

y = - 4x² - 4x + 8

To find the x- intercepts let y = 0, that is

- 4x² - 4x + 8 = 0 ( divide all terms by - 4 )

x² + x - 2 = 0 ← in standard form

(x + 2)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 1 = 0 ⇒ x = 1

Thus the x- intercepts are (- 2, 0 ), (1, 0 )

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00

where did you get them? if you picked from the grass, is is probably poisonous.
