Answer:

(x +1)² = 4
(D) x = -1 ±2

Step-by-step explanation:

Start by getting the x-terms on one side of the equal sign. We can do that by subtracting x from both sides.

3 = x² +2x

Now, add the square of half the x-coefficient.

3 +1 = x² +2x +1

(x +1)² = 4 . . . . . . . . write as a square in the desired form

To solve, take the square root, and add the opposite of the left-side constant.

x +1 = ±2

x = -1 ±2 . . . . . . matches choice (D)

Answer:

Distance between the police station and the fire station be 4 miles

Step-by-step explanation:

Let distance between the police station and the fire station be x miles.

The distance between the library and the police station is 3 miles less than twice the distance between the police station and the fire station.

Distance between the library and the police station $=2x-3$

Also, distance between the library and the police station is 5 miles.

$2x-3=5\\2x=3+5\\2x=8\\x=\frac{8}{2}\\ x=4\,\,miles$
