Answer 2

+9

Explanation:

The coefficient of the x term is -6.

To "complete the square," take half of this coefficient, obtaining -3.

Square this, obtaining +9. This is to be added to both sides of the equation x^2- 6x = 5, yielding:

x^2- 6x + 9 = 5 + 9

The first three terms on the left are now the square of (x - 3).
