Final answer:

To complete the square in the quadratic equation x² - 3x = 1, you would add 2.25 to both sides of the equation.

Step-by-step explanation:

To complete the square in the quadratic equation, we need to add half of the coefficient of the x term, squared. In this case, the coefficient of the x term is -3, so half of that is -1.5.

Squaring -1.5 gives us 2.25. So, to complete the square, we would add 2.25 to both sides of the equation.
