    Answer:

    1

    Step-by-step explanation:

    To complete the square, first you must make sure that the coefficient of the x^2 term is 1. Here you have x^2 – 2x – 36 = 0. Since the x^2 term is simply x^2, you do have a coefficient of 1 for the x^2 term.

    To find the number you need to add to complete the square, take the coefficient of the x term. Divide it by 2. Then square it.

    The x term is -2x. The coefficient of the x term is -2.

    Take half of -2 which is -1.

    Now square -1 to get 1.

    You need to add 1 to complete the square.
