Answer:

i find the design and functionality very coonfusing and poorly done, voice mail messages will not play, endlessly loading, even tried reinstalling, doesn't help, update: seems to be that you have to force quit the app and then start it again in order to listen to any voice messages, that is a major flaw and why has this been going on for so many months that I've lost count yet no one at the mighty Microsoft corporation seems to be competent enough to fix this?

Answer:

1) 5 2) 6 3) 1.25 or -1.75

Step-by-step explanation:

1. x^2 - 25 = 0

x^2 - 25 = 0

First, add 25 to both sides!

x^2 = 25

Now square root both sides.

x = 5

2.  (x-2)^2 = 16

First, square root both sides.

(x-2) = 4

Add 2 on both sides.

(x) = 6

x = 6

3. Quadratic Formula = -b ± \sqrt{b^{2}-4ac } / 2a

Substitute in:

-6 ±\sqrt{7^{2} -4(2)(6)} / 2(2)

-6±\sqrt{49 - 48} / 4

Both forms:

-6 + \sqrt{1} / 4

5 / 4 = 1.25

Negative:

-6 - 1 / 4

-7 / 4 = -1.75
