One x-intercept for a parabola is at the point
(2,0). use the quadratic formula to find the
other x-intercept for the parabola defined by
this equation:
y = 4x2 - 4x – 8

(2,0) was already given so (-1,0) is the other one.

Step-by-step explanation:

So we are asked to use the quadratic formula.

To find the x-intercepts (if they exist) is use:

.

Let's start:

Compare the following equations to determine the values for :

So

We are now ready to enter into our formula:

So the x-intercepts are (2,0) and (-1,0).

(2,0) was already given so (-1,0) is the other one.

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09
