Answer:
   B.  x = -6, x = 4
Step-by-step explanation:
The constant on the left wants to be 1, the square of half the x-coefficient. We can get it to be that value by adding 8 to the equation.
   x² +2x +1 = 25
   (x +1)² = 25 . . . . . . . rewrite the left side as a square
   x +1 = ±√25 = ±5 . . . . take the square root
   x = -1 ±5 . . . . . . . . . subtract 1
   x = -6 or x = 4
