How would start solving this example. Please help?

Question

Solve using the square root properly

(x + 6)^2 = 4

Answer 1

I would take the square root of both sides of the equation, getting:

x + 6 = +/- 2

x = -6 +/- 2

x = -4

x = -8

Another way is to square the left side getting:

x^2 + 12x + 36 = 4        

Subtract 4 from both sides.

x^2 + 12x + 32 = 0          

Factor

(x + 8)(x + 4) = 0

x = -4

x = -8

Answer 2

(x + 6)^2 = 4 (square root both sides)

x + 6 = 2 or x + 6 = -2 (subtract 6 from both sides)

x = -4 or x = -8 <===ANSWER

Answer 3

Take the square root of both sides. This will give x+6=2 and -2

x+6=2. subtract 6 from both sides giving x=-4

x+6=-2 subtract 6 from both sides giving x=-8
