What number should be added to both sides of the equation to complete the square? x2 + 12x = 11
36
121
6
144

Step-by-step explanation:

Take half of the coefficient of x (in other words, take half of 12).  This results in 6.  Square this result, obtaining 36.

Now x2 + 12x = 11 becomes x^2 + 12x  +  36   = 11  + 36, or

                                              x^2 + 12x  +  36   = 47, or

                                                  (x + 6)^2 = 47
