X2+14x=-7 what number must you add to complete the square

49

Step-by-step explanation:

To find the number we add to both sides to complete the square, we do b divided by 2 all squared.

(b/2)²

In this case, we have b = 14

(14/2)²

7²

49

  49  

Step-by-step explanation:

To complete the square, the second leading coefficient  divided by 2 squared will give you the number need to add to both sides.

For example,

14 is the second leading coefficient in the   so if you divide it by 2 you get 7  and 7 squared is 49.
