The answer would be the first one, (x-6)^2=31. To explain this first, you must expand and simplify the equation and it would look like this, (x-6)(x-6)=31. Then, solve and simplify the equation and will look like this, "x^2 - 12x + 36 = 31". Since 36 and 31 can be simplified more. Just transpose 31 to the left and it will become negative and it will look like this, x^2 + 12x + 36 - 31 = 0 Then the answer would be x<span>^2 + 12x + 5 = 0</span>
